i have spent 40 mins now reading the logs to see why my server crashes whenever I join to see farseer erroring out the server and basically chunk banning me but worse since the whole server crashes LOG : https://mclo.gs/ya6G8gS

Same issue.
Here is the crash log: https://pastebin.com/WBpUe8pv

Another thing to note is that this happens only on the server side!
Running a singleplayer world does not crash the map.
The error is about loading a model for the farseer. Maybe the mod tries to do it server side where it shouldn't?

I have InControl and I made a rule to deny any spawn or join of the mob in the world from any source (player, world, summon).
But this should not be the solution for this problem and I think we will not have a solution anytime soon...

Yeah that's probably it why is the server trying to load the model when it doesn't have a rendering engine to fix this I just place a command block at spawn which instakills them whenever they spawn

whats incontrol

InControl! mod is made by McJty and it has a complex system of defining rules about spawning. It has a wiki and some examples (it's quite hard to understand how to write those rules; it took me some days to understand some basic mob cap rules =)) ).
I've made the rule to deny any spawn of that mob and it's being removed before it actually spawns, so the model won't load.
