Seems to have some other new features I forgot about too.
You can set the map in a gamemode, there is a map wand (I don't think I finished that, probably does nothing)
Of course you can set the map with the custom gamemode UI, you don't have to do any fishy add-on enabling and wasting datablocks
I'll upload the modified maps, the static map mod and the example gamemode, but ya'll can make a thread since I'm not active that much anymore.
Just credit me please ;)
