I posted these two in the suggestions mega thread, but I didn't really explain them other than through bad achievement memes.
SO. Reservoir and Mann Co Hq were both removed a while ago because they had no working cap and because players glitched their way out of the map, respectively. I went ahead today and fixed them both! Also some minor re-texturing was done on both, but I think only reservoir looks slightly different since I edited the props on that map a bit too.
These two maps were always favorites (I think), and personally I loved them. Now that they're fixed, I'm just hoping they get added back into the rotation!
