Another huge problem it that when you rotate an object or group of objects, the rotation and position doesn't reset for the objects in the edit coordinates option, practically making it impossible to build unless you build everything at the standard 90 degrees. PLEASE PATCH THIS GAME BREAKING PROBLEM.
Never mind about the limits glitch, I was being a dolt.
A possible workaround for people with the object collision errors: make sure you are not copying doors. If you try to duplicate the same door, it gives you an error. I noticed when I created a new door every single time it fixed the problem. It's annoying, but it worked for me.
When I select multiple object, such as several fence objects, and then duplicate them, they do not stay lined up. They shift all over the place. I find that I must duplicate one object at a time. This is very frustrating. I have not seen any other post on any other forum about this problem. I wonder if it is just me. I use the Microsoft Elite controller. Maybe that somehow affects the movement. Anyway, please fix this if it is indeed a bug.
A bug that is coming up quite frequently. I select and object and hit the left trigger to reset the editing coordinates. Instead of setting them to the point I am looking at the coordinates instead leap out to some random location out in open space. Trying again to reset on the object only serves to exacerbate the issue. With three or four attempts the coordinates end up trying to reset outside the map limits.
