So this is getting a bit annoying, in the last 10 attempts I've made trying to upgrade a standard door to a reinforced door I've failed 5 times and lost probably close to 20 HP's! I get the stupid message saying that while I was attempting to install a 'BLAST DOOR' it fell on me! So obviously a problem there. As well just to clarify I have close to a hundred percent to install a reinforced door according to the equation on the rules page. I would have put this in the bugbase but I couldn't find the link. Thanks!
