yeah uh the thing is when you edit the contents of zips (by copying a file into it or removing a file from it) the game screws up. you have to do setmodpaths(getmodpaths()); if you're ingame and want to update the actual files blockland sees. you do not have to do this if you edit the contents of a folder, however, but if you make a new folder you still need to do setmodpaths(getmodpaths()); iirc.
