Really 2 problems, but most likely connected. First off - I am making a slight edit of an old trade map - trade_plaza. It's someone else's map, so this is why some bugs arise. Problem 1 - entity leak. I have a trigger push by a ladder. The compile log tells me it's leaking, but the map plays fine even with it (lighting is good and no other bug besides "probelm 2"). I loaded the pointfile and the line flat-out goes right through a wall. Don't know whether the one nodraw-ed side is contributing to this, but this just seems odd. problem 2 - the water in the middle of the map now leads to the void. This happens when you mess up creating the water. Like when walls are not touching other walls or you don't nodraw all sides except one, but I did all this. I created water before and I have no idea why it's not working in this instance. The water was even there from before I touched the map. I did something and now it's like that. Tried copy/pasting the old map parts back, but nothing changes. My guess is that it was something to do with problem 1 - the weird leak. But as usual - with all my questions on these forums, it's probably some idiotic mistake I made.
