I know who he is and isn't. The fact he doesn't work for PG didn't stop him commenting on the issue originally, why should it stop me responding to his post?
I didn't say it was related to roofs. It does however show that it is just as likely with these devs that it's a bug with the roofs, as the game is full of bugs. The poster may not work for PG but he sure likes to defend them at every opportunity and assume they must have a good reason for doing everything they do, rather than you know, being lazy or incompetent.
