Crash when starting simutrans server

[Dreedo]

Hi, my Simutrans server program was working before, but now when i boot i get this error, regardless of which pack i use. It's in German so i don't know what it says.

Fatal error
fabrik_t::rdwr()
no besch for Kohlegrube
PRESS ANY KEY

Thanks.

There's an object "Kohlegrube" in a save, but not loaded in the pakset.

Ok thanks, i sorted the problem just now by using a seperate simutrans copy i had on my HDD. But this will help if it happens again.
