Server is crashing when trasher is attacking

[Moldx3]

Hey,
i am experiencing issues with the trasher.
Nearly always when it attacks and grabs a player and throwing him around the server crashes.
I've just updated forge, upgrade aquatic and blueprint and the issue is still present.

Can confirm we are having the same issue with mod version 5.1.0 on MC 1.19.2 running Forge version 43.2.21 on MP Server. The issue only effect the Thrasher and not the Great Thrasher. If it grabs a player, the server crashes after a second or two. Can't remove mod without corrupting world. Had to add a repeating command block to constantly kill thrashers to prevent the crash.

I'm seeing it affect Great Thrashers as well.

I had a similar problem on my server with upgrade_aquatic 1.18.2-4.0.0 and blueprint 1.18.2-5.5.0 on forge 40.2.9

the crash log looks pretty identical but one of our players fought thrashers and got grabbed twice without the game crashing--the closest person to the thrasher was foggyboots and he was on an island

@teamabnormals Is there a fix for this on 1.19.2? I just had this happen to a few people playing my custom modpack and was wondering when will this be fixed so that they don't have to keep disabling the mod

Are there any plans on porting the fix to 1.19.2 as well instead of just 1.20
