Getting a recurring SMP server crash when players are killed by a zombie chicken rider.

Here's a copy of the crash report:

crash-2016-12-20_00.08.52-server.txt

From what I can tell by tracing the crash, it doesn't appear to be related to Baby Mobs. The crash is caused by the TombManyGraves mod; this code in particular. It looks like the mod is scanning the player's inventory after death and encounters an item with a null enchantment that throws the null pointer.

I can't replicate the crash with Baby Mobs, TombManyGraves, EnderIO, and EnderCore installed, so I can't know for sure, but I would assume that this crash is related to a specific item in the player's inventory when they die. If that doesn't appear to be the case, I can try to replicate the crash if you give me the mod pack that it happens in.

thank you for the explanation and help tracing this. i am no expert on reading the crash files and it only seemed to be happening with that one mob (3 times so far) but coincidences do happen. will try checking for a bugged item next. if it is not an item and i am able to reliably replicate the conditions i will post again with the details.

thanks for the quick reply. love the mod.

No problem, I'm glad you're enjoying the mod!
