Actual Behavior

Steps to Reproduce

My server is crashing. this happen with the mod Animania Farm. with the Leghorn rooster/Leghorn Hen and the only way to fix is deleting them. before i crash again.
and i believe this is happens every time after i pick up them using this mod.
pick up them is making they corrupted or something.
i already read some issues and i saw another people having the same error. with other mods
the crash will not happening right way. you pick up them put in the ground them 10m maybe some times 20m the server will crash. and then you need deleting them to stop the crash.
if i never pick up them. the game never crash i played for 10h and 0 crashs and the rooster and leghorn there. but i forget to not pick up them. i pick up one only one time. them 10/20m the server crash .
Well only let you know. i will try remove this mod. and test for some days/ i will tell if i crash again or not
ahh the game crashed too. with some other mob from other mod. after i tried pick up him up. "scape run parasites" i believe is the mod. exactly same error
thank you
