I think the problem is that you remove the location "ATempRegion" and afterwards use it and set it again. But since the location is removed, the following functions like "set ..." and also the "create unit..." won't work.
If ATempRegion is a local variable, just remove it at the end, if not, you don't have to remove it at all since you just set it to a new value every time and that doesn't cause any leak.
