It would be my luck that last night I was standing in front of a Large in Shirogane, Plot 37 Ward 18, on Cactuar, and I couldn't relocate because of this error:
"Unable to execute command. Housing functions are currently locked."

Not going to lie, after trying for a large house since be beginning of time, I felt utterly defeated. I guess this is just my luck that I would get this random error. Eventually, someone else came along and relocated their FC house to it, so I lost my chance. It's one thing if they are just unavailable and someone beat me to it. It's just wrong if I get there and I'm just not able to purchase because of some error, and then watch someone else come along to buy it.
