Hey guys I'm funning my own ftb server with the Ultimate_server and things were going well until this happened.

Any idea on how to solve this?

Anyone?
I can get on the server but as soon as I press E for the menu it crashes

Try deleting your player.dat file.

 

[Vikanug]

I already have done that a few times now and still never worked.

 

[TheSandwichMakr]

Try deleting the .dat files in worldname/EnderStorage backup your world first though because this will remove everything from your enderchests and tanks.

only buckets of lava in my enderchests since I had a lava loop from the nether to the real world. I'll try it and will let you know if this works.
