Just had this ticking entity crash upon entering the map

ive just added I like wood + byg comp expansion (these are not in the current release might release later tonight)

havent really had it before

here is the log
crash-2021-10-05_05.02.31-server.txt

and this is the pack it happend in
https://www.curseforge.com/minecraft/modpacks/chosencraft

Sorry, but the stacktrace doesn't point out anywhere in my mod. There's this line:

Entity's Vehicle: ~~ERROR~~ NullPointerException: null

That may be causing it, but I do not touch vehicles/mounts anywhere in the mod, so there's nothing that could be bugged to begin with. Can this crash be reliably replicated with these mods?

When minecraft crashes, a latest.log file should be generated in /.minecraft/logs, could you attach this file so I can take a deeper look into it?

Closing due to lack of information
