Level editor crashes when placing entities

[burge4150]

I have reinstalled the editor with no success.

As for navigating to that path, it's not even a real harddrive location, notice the /'s are backwards from a directory path.

Also, it seems the crash doesn't occur just when placing entities. I opened an existing Amnesia game map to look around it, and after scrolling around for a moment it crashed with the same type or error.

The maps, however, do not crash until entities or doors or such things exist on them. Walls and floors do not cause the issue.
