Um, your kinda screwed? If you mess up the money glitch, it is messed up and there's no point of return, short of starting over. But did you delete something or what? Cause sometimes I found that all you have to do is start a new round. As for the second map, what is the issue? Cannot you not place weapons? Cause that doesn't make sense, unless that money glitch got messed up too... As for the elevators. It could be the height, but from what I can tell, the main reason you don't like them is that the top mancannon launches you forward, hence the barrier wall. Have you tried the elevator without the top lift/cannon?
the only thing you can do is delete stuff until you get money back that will undo the the money glitch. And then set the money glitch again on the things you want.
The second map has weapons and the only problem with the elevator in the second one is that you hit the barriers so hard they tend to shift and well the elevators are a little crazy buecause you'l go into the elevator and end up on the other side of the octagon lol. the first map is the one where theres no weapons I have about 5 I cant place that I havent deleted. also I think I was tele tapping and somtimes whne you start a new game with the money glitch all the maximums are at minimums and I saved it when it was like this (because i was tele tapping) and thats why its probably screwed
