Deleting BSP and undoing that delete breaks the engine


When I delete a BSP box and then undo that delete suddenly I’m not able to edit the surface materials anymore, nor does it even allow me to select and delete the BSP box again. And doing undo after that also no longer works, so you’re basically stuck with broken BSP at that point. You then need to re-open your file basically…

Can anyone confirm this?


What engine version you trying this in?

The latest, 4.10.4
