You can use Whirlwind Enemies, and I assume Whirlwind, to move the reinforced door around the map. I'm not sure if this is a bug I guess it depends on how reinforced the door is. Either the mighty whirlwind can rip the door off its hinges, or the mighty door can withstand even the strongest winds, either way is fine, I just thought I'd mention it ^_^ Like this thread: http://www.cardhunter.com/forum/threads/reinforced-door-vs-los.1436/ the behaviour is probably a result of the door essentially being an Immovable enemy.
