Hi, I'm pretty certain that the Property Registry feature in Cordor (And likely wherever else) doesn't actually show shops/quarters that are up for bid, only those that are able to be instantly bought (The old system).
For example, there's a shop for bid in the Cordor Colosseum, yet the Registry states it is owned.
It would be neat if this could be fixed! Not sure if it's possible or not, but thought I'd suggest it.
