Minor bug in the java editor - if a multipart object spans tiled maps, the editor is unable to load the map - it throws an exception. An example of this is the world_121_116 in the maps-bigworld directory. But it wouldn't be hard to immitate - just put the head of a multipart object at the far right or bottom of a map. I haven't looked at the java code. The right thing to do would probably just link in the parts that are on the map in question, and ignore the parts off the map. This might mess up some cut/paste operations, but this is probably a pretty rare occurance. Thought I should at least mention it.
