Playing around with this map a little yesterday I've noticed this glitch near T to A entrance when looking at the bombsite:

You should be able to see a faint red line on the same height as the bombsite's floor go right through the wall, I'm not sure what could cause this or if it's even map related, just thought I'd let you know.
