With the ability to make your own NPC's and using other mods to arm them, it is extremely important not to arm them with weapons you do not know, especially player made weapons! I make lots of backups thankfully, otherwise my ship and space station would be toast for good. I logged on to find not only my space station missing large portions of itself, I found my ship to have the same issue. Turned out the NPC's on board I armed with player made weapons, ones that open a black hole. Other players had spawned monsters on both ship and station and when the NPC's used these weapons to kill off the monsters, they destroyed huge sections of the ship. I have since removed and destroyed the weapons, but figure I put a warning in here in case you use this mod with the arming one.
