Possible bug?

[{HHx}b14ze]

When i use the tweaker on a certain piece of the dam, a bridge part, i change the Y value and the editor crashes? Is my editor not set up right, is it a bug, or am i doing something wrong?

probaly a bug, as this is intended as a "beta" editor.., yet i dont see EA in a rush to release any updates.
