Cant Save World - Failed to Save [21, 2] aztech.modern_industrialization.pipes.api

[viscid badger]

Hello, every time i try saving my world i always get this error: ```
java.util.concurrent.CompletionException: java.lang.NullPointerException: Cannot invoke "java.util.Set.remove(Object)" because "set" is null

Caused by: java.lang.NullPointerException: Cannot invoke "java.util.Set.remove(Object)" because "set" is null
at aztech.modern_industrialization.pipes.api.PipeNetworkManager.decrementSpanned(PipeNetworkManager.java:339) ~[Modern-Industrialization-1.6.18.jar:?]

Can someone help me diagnose this? I've looked everywhere on the chunk and i cant find anything odd.

That’s not straight AoF, is it?
I thought smallships was taken out of AoF6 quite a while ago.

i've readded a few mods that were removed and a few QoLs

[terse locust]

Hrm. We’ve seen bugged MI pipes in the past (rarely), iirc.

I’ll see if I can find any posts relating to that.

Btw, you mentioned in an earlier post on #all-of-fabric-6 that you think this is causing data loss… can you say more about that?

[viscid badger]

iirc Minecraft saves every 5-15 minutes, when the game saves it like that (i presume it async saves modified chunks) its fine

but lets say i made a change 3 minutes after the "async save", if i try to save and quit that data will be lost

[terse locust]

Just to clarify... are you assuming it will be lost, or is it actually lost?
Is your game not able to quit all the way?

honestly, that error log is extremely difficult to sift through because you added mods that quite clearly conflict with one-another 😐

given the error, i would suggest removing MI pipes from the region specified:

blocks from 336,32 to 351,47
at all levels

[viscid badger]

Nope, it cant quit at all

[viscid badger]

is MI known for doing this often?

if so i guess i'll avoid using pipes from now haha

[willow rune]

nope, this is probably the second time in a couple years i have seen it

[terse locust]

Glad Ling came by and got you sorted. He’s awesome like that.
