Level editor occasionally doesn't allow placing Thangs unless reloaded

From time to time, the level editor seems to get into a state where I can’t add thangs any more. To fix this, I have to back out to the level list and re-initialize the editor.

I’ve had this happen multiple times, and the most frequent trigger seems to be after deleting a thang (via selecting it and hitting backspace). Once in this state, I can select thangs from the list on the right, and I can move it into place with my mouse, but when I click, nothing is added to the map.

Has anyone else experienced this?

Edit: And like the good user I am, I didn’t read the instructions to post bug reports to Github instead of here until after I posted… sorry.

Should be solved now!
