I feel like this might be some kind of incompatibility with either Cracker's Wither Storm Mod or Sculk Horde, but from looking through the logs I am seeing errors about the Anteater mob and errors saying "attackTarget" is null. This is only happening when I have the Wither Storm spawned in at phase 4 and with the Sculk Horde active (i've only tested it with both at once, it could be caused by either one). I also had a similar error a while ago but it said something about an error involving the crow mob but I don't have that log anymore. Here is the log from when the crash happened
