Wood window + metal bars structure is destructable?
There seems to be a glitch on the metal bars, though. I put 8 Explosive Charges on mine the other day (doing a little remodeling) and they would not blow. The wood frame, however, yeah - no problem.
I just had the same issue, not sure what is up with that.
Also, just noticed the use of the SometingAwful emoticons. Excuse me while I go put stairs in my house.
