Glitched Buildings

[Lorenzo666]

Right, so I bought up two buildings in Brink, and then a little while later I saved and loaded too quickly, causing all the NPC's to disappear and half the town, because I hadn't let it save properly, I did a new game with my squad and buildings imported (I don't really wanna lose 42,000 catans worth of property now do I?) and now, the buildings that I own which were imported, also have their original selves inside of them and the pathfinding is extremely glitched and the doors sometimes fail to open.

Is there a fix for this or am I stuck like this?
