Cant save with new doodad

If i edit or create a new destructeable/doodad the world editor wont let me save, i get a "Unable to save file XXX" error. I will get this even if i just edit the name of a tree or something like that.

Anyone know if this is fixeable?

That's a strange error. Are you using a customized WE?

Have you tried re-installing the game?

Actually i figured out what it was.. pretty stupid, the map was a w3m file so the editor ofcourse couldnt save the new TFT stuff into it. Thanks though.

I'm glad you figured it out, although I'm accustomed to the WE changing the map from .w3m to .w3x as the occasion requires.

Yeah, i assumed it did that, but apparently it didnt.
