Alright, I was indeed able to fix stations with commands, but it did require quite a few DungeoenID-specific /settileprotection x false commands. The generic "0" only unlocked most of the station walls; some blocks in the walls needed an unlock via DungeonID, then the space part that is still in the cube-shaped area the game thinks the part occupies, and then the space around the station. If you do not know how to do this: /admin => toggles admin mode; required for the other commands /debug => displays debug-info, including the dungeonID of the block your cursor is pointing towards /settileprotection x false => replace x with 0 or the dungeonID of the tile you want to unlock; unlocks the corresponding area. 0 is some kind of general location-based input, I'm not entiely sure about the specifics. /entityeval object.smash() => hover your cursor over the background image(s) or expansionslot(s) to remove them. Images should drop in itemform, expansionslots won't drop anything. It should be noted that this still requires admin privileges, which means it is impossible to do for most people playing on a server.
