Player repeatedly crashing while others play with no issue

[Shirby]

Hi!

We just recently started playing on our (very modded) server with a few friends. We managed to play for a good 2 hours without any issues but then one friend suddenly crashed while in a forest, falling down. Everytime he rejoins now he crashes again and gets the following logs. 

Would greatly appreciate any help as I am rather clueless at this point, thanks ahead of time! (And I hope this is the right place to post it)

not sure but it seems like it is combat ovehaul that causes the crash try to remove that and see if the crashes persists.

if not just add that back but it seems like there is something targeting something, and the issue might be with an entity

Thanks a lot! That was it! He can join now.

I suppose its hard or not possible to read what its from? Since we have 2 mods that add a few more mobs.
