Found it by now, you have to exit the bot to create the file ^^
But the reaction is slow, i saw it saying that a hostile entered the system, it was just an alliance i didn't add yet so no biggy but it took the bot about 30s to get the drones in and init warp afterwards. Well it could be worse like after it warped to my safespot the bot unloaded, continued the hostile spam and started to warp back to the last bookmark!
Edit:
Looks like somewhere in obj_Ship where it warps back to the bookmark it doesn't check the Social.IsSafe() ^^ or in a file that controls the obj_Ship....hmmm ^^
