A Rimworld of Magic - Wandering Lich event bug

[DevilstrandMender]

I've been playing with this mod for a few months and i've always had this problem. Everytime the event ¨Wandering Lich¨ happens the skeleton lich and the other skeletons start attaking eachother... is this normal? if not, how can i fix it?

I tried forcing the event and i started getting this error

Wanderer didn't  follow the forum rule, so don't be surprised when you topic get moved or deleted.
Read the stickies of a subforum first before you post (and not only here).

Since you notice it isn't a vanilla bug, you should ask the mod author about it.
First be sure it is that mod only.
Deactivate all beside rim of magic and the required mods.
Use hugslib feature quick launch (top right icon) to create a fast test colony.
Try to execute the incident Wandering Lich (debug action menu, incident (map).

If the error still happen, try to manual delete the mod folder or when you use workshop unsubscribe so all local data get deleted and resubsribe.
Then try it again.
If the error still happen, you should report it to the mod author, since he isn't at the forum anymore you should do that at their discord channel, maybe at the workshop discussion.

When you don't got an error overall, then any other of your mod's didn't works well together with Rim of Magic, you can try to move rim of Magic at the end or at the top to check if that fix the problem.
If that don't help, it is hard to say what mod cause it.
