Hi, I know it's an unstable version. The case is that the mods are not being loaded. From what I can see it's a problem with parameter of the server startup.

My guess there's a problem with this

LOG  : General      f:0, t:1765593637132, st:46,079,170> unknown option "-Duser.home=/home/sid_8487787/Zomboid_unstable"

but the mods download correctly

but after that mods are missing to load

I've tried adding another mods folder via the FTP, also the mods are configured properly from my understanding

Mods=ModernStatus;NeatUI_Framework;Project_Cook;Project_Cook_Pixel_Icon_Pack;CleanHotBar
WorkshopItems=3451167732;3508537032;3490188370;3461263912

I'm having the same issue, no solution yet

After doing a bit more digging I agree, I believe the issue has to do with the Unknown option you pointed out. My mods appear to be installed and set correctly, they even appear in the mods list in game yet all of them say [Not found] even though they are present on the FTP.

Hello to the both of you 🙂
I'll ping our helpers <@&1339607962850951238>, but to be honest, this seems more like questions for tech support.
Please contact them and let me know if you run into troubles or when it's resolved. Thanks! 🙂

Somebody has messed something up, usually there’s no space between -D and your option.
You can modify the .json file and set a space between -D and user…..

#

Regarding B42 MP:

This is unknown territory.
Devs advised not to use any mod for now.
If you need help with something like that, please visit the official PZ Discord. The have a dedicated Support for that.

Ok, I found the solution. Apparently mods in the list should prefix with \, so eg: \ModernStatus;\NeatUI_Framework;\Project_Cook;\Project_Cook_Pixel_Icon_Pack;\CleanHotBar;

Tried this, but im now crashing when loading into the game

jolly wadi Dec 15, 2025, 1:52 PM

Visit the official PZ discord and ask tech support.
B42 MP is still unstable.
Like i said, DEVs do not encourage people to use Mods as of now.

#

So i cannot help you with anything related to B42 MP and Mod Support.

leaden ermine Ok, I found the solution. Apparently mods in the list should prefix with `\`, so...

This worked for me as well, just tried it. The server-console log still returns the errors though, but the mods work. I have tested only for myself, not sure if it works for someone else who doesn't pre-install all required mods by the server.

#

The root issue is that when the mods are downloaded they are placed inside a 'mods' folder inside their workshop ID folder, for example: \ 108600\ <workshop_id>\ mods\ <mod_name>\ ...
And that is not aligned with how the server looks for and identifies the mod paths.

Then this must be a recent change That would explain some issues on every branche of PZ

Since the OP of this thread left the server and with regards to my mentioned solution, i am going to mark this thread as solved for now.
If you have further questios please open a new thread or reopen this one.
