Hey guys!
We just patched the game to properly support Workshop maps. Apparently, there was some new unit functionality that the older maps did not support and we didn't catch in our last build.
We would like to remind everyone that you should load and re-save out your existing workshop maps if you have created any. Properly updated maps will be given preference in our highlighted maps listing in skirmish and multiplayer modes.
Have fun, and thanks for your patience!
