Would assume this is pretty rare,as i have never seen it happen before.Finished an adventure and was waiting for my QM Claus to return,they tend to return to star menu with a popup saying no room available on the island,but this time the one Claus removed a gold tower to steal its spot and sent it back to star menu.Not really a big problem i suppose,as the tower doesn't need to be leveled up,but a thankfully rare glitch all the same. Anyone else have this happen?
