i teleported somewhere on the map (-8000, 80, 8000) and everywhere was oceans, and there was a battle tower from atomicstryker, after 2 seconds i look around, it crashed..

Could you send me the world?

EDIT
Wait i failed, could you redownload the file, now it should work.

yeah... the fresh world.. run and crashed only 1 time...
New Ezterian World.zip
and you can find the modpack in my github profile, as you know. its called Ezteria

Have you redownloaded it?

when? xD i just downloaded it 1 time
oh i see your edit now... going to retry

hey ah, i'm late sorry about it. i just installed that jar and run the game then created a new world, and it crashed directly after world generation.
