• I am running the latest mod versions of MCA and RadixCore.
• [] I can reproduce this issue with just MCA and RadixCore installed.
• I can provide my Minecraft version and MCA version.
• I have searched for the issue previously and it was either not previously reported, or previously fixed and I'm having the same problem.
• I am crashing and can provide my crash report.

MC 1.10.2 MCA 5.2.3

Server crashes shortly after restarting, from the crash log I beleive the error originates within mca.entity.EntityChoreFishHook

Start the server (I have a small server instance as I recently made a new one using my usual set of mods), I can zip up the server instance and provide it.
