[SOLVED] How to detect which mod causes the crash | Project Zomboid | Page 1

fallen night Apr 2, 2026, 6:13 PM

#

I play with a bunch of mods and recently my world always crashes and tells me to look in the console-log file but when I try to search in there, I only find a bunch of errors which I don't understand. Anyone got an idea on how to find out which mod causes the game to crash except restarting it over and over with every single mod only...

#

look for the error right before the crash. You should see a workshop ID somewhere around there. That's the mod that's crashing the server.

sour geode look for the error right before the crash. You should see a workshop ID somewher...

looks like the actual error was printed earlier in the log. seach IsoWorld.init and see if there is a workshop ID near one of those errors

#

maybe search java:2704 if IsoWorld.init pops up too many things

sour geode maybe search java:2704 if IsoWorld.init pops up too many things

IsoWorld.init only showed me this (except the end)

ngl I can't see a workshop ID anywhere in those screenshots. Are these the last errors in the log before the crash?

#

typically you'll see a 'server stop' or something like that right after

#

how many mods do you have?

fallen night Apr 2, 2026, 6:44 PM

#

there are a few errors give me a minute to look for more

fallen night Apr 2, 2026, 6:44 PM

#

sour geode how many mods do you have?

should be around 20-30

sour geode Apr 2, 2026, 6:45 PM

#

ok not too bad. like I said earlier, it's typically the last error before the crash that shows the reason (if it's mod related then it would have errors loading the mod).

#

also, make sure you've added in all the required mods for the mods you have, and check the load order. It's important that your core libraries (damn lib, phunserver, tsar's common lib, etc.) are loaded in first.

fallen night Apr 2, 2026, 6:47 PM

#

i thought the mods activate the libraries automatically

#

but they should be all on as I checked my list like 10 times

#

that was thr last error i could find talking about a mannequin idk

#

wait

#

what does "SEVERE" mean?

sour geode Apr 2, 2026, 6:49 PM

#

uhh idk 😅

fallen night Apr 2, 2026, 6:49 PM

#

there are a bunch of these at the end let me take a closer look rq

sour geode Apr 2, 2026, 6:50 PM

#

did you add map mods?

fallen night Apr 2, 2026, 6:50 PM

#

yes

#

but its only 1

#

i think

sour geode Apr 2, 2026, 6:50 PM

#

maps are a bit tricky

#

what steps did you take?

fallen night Apr 2, 2026, 6:52 PM

#

wow ive been timeouted for "links" which I didnt send wth

#

anyways

fallen night Apr 2, 2026, 6:52 PM

#

sour geode what steps did you take?

wdym

sour geode Apr 2, 2026, 6:52 PM

#

did you add the name of the map to the Map line? (typically line 78)
and sometimes you need to add the map folder to the maps folder in media

fallen night Apr 2, 2026, 6:52 PM

#

no i just activated it as usual

sour geode Apr 2, 2026, 6:52 PM

#

remove it and restart

#

see if the server starts up

fallen night Apr 2, 2026, 6:53 PM

#

ok

sour geode Apr 2, 2026, 6:53 PM

#

if it does, then do some research on how to add maps

fallen night Apr 2, 2026, 6:53 PM

#

where is the line if I may ask

sour geode Apr 2, 2026, 6:53 PM

#

maybe talk to your host if you're using a dedicated server

sour geode Apr 2, 2026, 6:53 PM

#

fallen night where is the line if I may ask

what line?

fallen night Apr 2, 2026, 6:53 PM

#

im on sp

#

not mp

fallen night Apr 2, 2026, 6:53 PM

#

sour geode what line?

where is the line which I have to edit?

sour geode Apr 2, 2026, 6:54 PM

#

line 75 & 218 for me

fallen night Apr 2, 2026, 6:54 PM

#

in what file?

sour geode Apr 2, 2026, 6:54 PM

#

that's the workshop id and mod id

#

the zomboid.ini file

fallen night Apr 2, 2026, 6:55 PM

#

alr

sour geode Apr 2, 2026, 6:55 PM

#

.cache > Server > Zomboid.ini

fallen night Apr 2, 2026, 6:58 PM

#

uh i cant find that file 💀

#

nor the .cache folder

#

i looked in both the zomboid folder and in the steam pz folder

sour geode Apr 2, 2026, 6:59 PM

#

C: > users > (your name) > Zomboid > Server > you should see the ini file there

#

sry I was directing with the mp path lol

fallen night Apr 2, 2026, 6:59 PM

#

oh its the files to the dedicated presets that I made long ago

#

do i need them in single player?

sour geode Apr 2, 2026, 7:01 PM

#

I'm not sure where to find it in single player. you might have to look that up

fallen night Apr 2, 2026, 7:01 PM

#

ok

sour geode Apr 2, 2026, 7:02 PM

#

it says what I said so I'm not sure why it isn't showing up for you shrug

fallen night Apr 2, 2026, 7:04 PM

#

is it named mapline?

sour geode Apr 2, 2026, 7:05 PM

#

fallen night is it named mapline?

what are you referring to

#

where to add the map details?

fallen night Apr 2, 2026, 7:06 PM

#

yeah

sour geode Apr 2, 2026, 7:06 PM

#

it should just be 'map=muldraugh,ky'

fallen night Apr 2, 2026, 7:06 PM

#

you said its typically line 78 but there is only a voidbox or smth like that

sour geode Apr 2, 2026, 7:06 PM

#

or something like that

#

you'll add it before muldraugh

fallen night Apr 2, 2026, 7:06 PM

#

there is no map=

sour geode Apr 2, 2026, 7:07 PM

#

(new map);Muldraugh,KY

#

there should be

#

in the ini file

#

search muldraugh

fallen night Apr 2, 2026, 7:07 PM

#

perhaps im in the wrong file

#

couldnt find muldraugh either

sour geode Apr 2, 2026, 7:07 PM

#

yeah you're in the wrong file

fallen night Apr 2, 2026, 7:07 PM

#

let me look rq cuz it seems its the general settings of the game

#

oh right...

#

when I try to create a world it just crashes and therefore doesnt create a world

#

it looks like this
just a usual crash

sour geode Apr 2, 2026, 7:11 PM

#

hmm ngl that's about as much as I know

#

sry

fallen night Apr 2, 2026, 7:11 PM

[NOT SOLVED] How to detect which mod causes the crash

fast harness Apr 2, 2026, 7:34 PM

#

fallen night IsoWorld.init only showed me this (except the end) ``` ERROR: General f:0, ...

that issue is with an ammo mod

fallen night Apr 2, 2026, 10:52 PM

#

An ammo mod can cause that?!

#

I‘ll definitely take a look on that tomorrow. I‘ll update in here afterwards

fast harness Apr 3, 2026, 5:49 AM

#

fallen night An ammo mod can cause that?!

yup, I had a similar issue a few updates ago, and it was because they added/changed some ammo types...

btw, any mods that add scripts can prevent the server from loading if the script is flawed/not updated.

fallen night Apr 3, 2026, 9:17 AM

#

It FINALLY worked! I checked every single mod page at the end and then turned on the error magnifier mod (should've done that way sooner tbh) and it told me about all the broken mods and then it worked! Finally able to play PZ again :D

#

thank you all for the help btw
