many of the NPCs in starbase 1 seasm to be have been pushed around and are now standing around in corridors are are away from their consoles. i cant even find maclom sissel or what ever his name is who hangs round in space dock.
This is only a theory, but there have been cases of where a KDF player can get into ESD (I only know of two myself). The NPCs will attack and follow them, but don't have the script to go back to their original position, so they just start their default animations where they stand. Admittedly though, it's highly improbable for all instances to have received a KDF "guest".
