Hey ho!
You did not mention the castle in that previous thread: CloudTrapezing into a friendly but besieged Castle causes the CloudTrapezers to teleport right behind the safe and cosy castle walls! I recall that I suffered exactly from this when hunting Ulm in our common ongoing game...
I think the game is missing the analog to "move and patrol" like "teleport and patrol"...
Sorry that I didnt recall this when you asked your first question, honestly...
