Implemented Can't log in

I can't log in cause the server is immedietly crash. Last thing i know, around my claim a "boss" Pech attacked me with potions, but i stay to close and the potions are effected reflective to him, after that the server is crashed. 10 minutes ago

 

I think the chunk is corrupted, after 3 hours the server is still crash when i try to join

 

@Administrator Would you be able to give the problem for the crash?

 

No, not duplicated. Crash from hellfire is happened once, 1 day ago, and i joined back, without problems.

But now, something else cause the crash because right after i join server crash everytime.

 

ok, problem solved Thank You!

btw, what is happened? newer version was came out and the modpack stoped working?
