The game crashed: rendering entity in World
Error: java.lang.NullPointerException: Cannot invoke "net.minecraft.world.entity.Entity.level(" because "entity" is null

So i have this one issue with the crash report above. I will be leaving the full crash report below but i think the main problem is because of "highlightTarget" and/or "player_relations".
It is so intense of a problem that once it happens, the only solution is to turn off the mod and load the save, then save and exit and turn it back on.
I've tried adding "minecolonies:citizen": "FRIENDLY" to client.json5, and changing "highlightTarget": true to false, but neither solve my problem.

here is the full report:

crash-2025-10-21_16.15.17-client.txt

We had no such issue with literally thousands of other mods.

Added some safeguards specifically for Minecolonies, I hope no more are needed.
