weird things with my DE server

[Sneaker-78- 0]

i have some weird stuff going on,

we where playing warfare and some guys joined and left no big deal , but after 30 min a new player was connection and then the server crashed, and i restarted the server but the AI is totaly gone and we can not see wherre we are on the map because its empty.

I replaced the mission because i thought it was corrupt, but no change even after i restarted the server there where no changes

So what happends with my server
