at thut.api.OwnableCaps.attachMobs(OwnableCaps.java:281)

Steps to reproduce:

1.use the mods listed here
mods.txt

2.load a virtual server and have a player try to connect
3. get the problem mentioned above
...

logs:
debug.log
latest.log

Affected Versions (Do not use "latest"): Replace with a list of all mods you have in.

• Thutcore: thutcore-1.15.2-7.2.1
• Minecraft: 1.15.2
• Forge:31.2.9

this is also affecting singleplayer world too
latest.log

hmm, one of your mods appears to be doing something it shouldn't be.

The particular error is thrown by this line of code:

https://github.com/Thuts-Mods/ThutCore/blob/1.15.2/src/main/java/thut/api/OwnableCaps.java#L281

This means either p is null, or the output of getCapability(ThutCaps.OWNABLE_CAP) is null.

Neither of these are allowed states for those values.

Can you see if you can find which mod is required for this to occur? ie, in single player, remove half the mods (except the elevators/thutcore), see if it still occurs, if so, add back the half you removed, and remove half of the ones you did not, repeat until the crash doesn't occur (or if it occurs with only thutcore and the elevator mods, link the new logs with just those two)

might be related to but unsure need to test more AlexModGuy/Citadel#9

the stuff mentioned in that issue is definitely is what could be causing this issue
