Level editor crashed

[goodcap]

My map worked fine yesterday (in-game and in the level editor) but today it only works in-game. I checked the log and I seem to be dealing with corrupt entities/static objects.

Is there a way to delete those without using the level editor. If not, I can never use that map again..

I was kind of expecting this to happen. because I noticed a floating painting in-game that was nowhere to be found in the level editor.
