When using undo after having edited brushes the engine will sometimes crash. Unfortunately I can't provide exact steps to reproduce as the issue is random and typically rare, I only get it on my map every few days when editing specific brushes then undoing that move. As suggested I'm opening this and attaching the two GDB backtraces I got during two different such crashes, one after undoing a brush selection move the second after undo following a heightmap edit.
