when i kill creepers i get Connection Lost internal server error

[demaxer]

i am running a forge 1.7.10 server with 15 mods.

it happens only with creepers nothing else i think, the bug has probably been there from the start but we havent noticed it until i killed one.

one time when i put a bucket of lava on 2 creepers the server crashed then also.

 i think it might have something to do with the bicBiomeCraft mod because that is mentioned in the crash report, but i dont want to remove bicBiomeCraft because then i would get alot of invisible blocks.

i either want a fix to this bug or just remove all the creepers from the server. 

 

when ever i get kicked i get this text:
