Comment 3 for bug 736460

I've tried looking into it, though I haven't had any luck finding where the issue is. The tileset variable is set correctly in the editor because it loads, but it just doesn't seem to make it to the save function.

I don't think I'll be able to fix it any time soon. I haven't looked at it but I've got a hunch that the problem lies within the function that takes care of saving. At the very least that function should assign a default tileset if it doesn't get sent one.
