I was making a map, then I decided to test it. I did not die, but when I came back to the editor, it spams the chat with "Thanks to Phanghuang, we gathered 0 cheese!" also, I am unable to edit the color of the grounds after that. It gets really annoying and I have to constantly leave and copy the XML so I can continue the map.

Have you tried to relog?

That's only a temporary solution to what seems to be a permanent issue.

Could you give us the XML? (You can PM it to me if you want) There might be something in it that's causing autodeath.
