[mAAp]Square - again found maybe something to correct (sorry). when you are on top middle tower, you can jump beside on the broken part (see picture http://postimage.org/image/5eodk104z/ ). but then - and this is also at the current version - you can not enter the building again. but you should, if you are crouching i guess. maybe you can fix/allow that?
Looking at this, it would be a bit of a pain to try and make the hole bigger or something. The easiest and quickest way to solve this problem is to just add a playerblock so instead of falling in the hole, you just slide right off. I agree that it would be cool to jump in there but I would have to remake that entire hole and I'm not too good with complex BSP work.
*EDIT*
I'm thinking that we're pretty much good for a release. Is there anything outstanding that hasn't been fixed yet? I haven't seen many map updates lately and I can't think of anything major to fix.
