Messed up tiles.

K so everytime I start the editor as of a few hours ago I get this really messed up image and when I go to select a tile I get nothing. I am guessing that it is because I have gone on a few different player made servers? Really annoying. Can somebody help me out, Anybody else had this issue?

make an NPC, put this script in it


Run the level. All fixed.

it happens when you fuck up an addtiledef.
