We've been playing in a 2 player multiplayer world. Both of our clients are set up with the 0.9.5.7:f version of ACE. Thanks to the update, we started a new map with a new world in case there were any conflicts.

Which was a bit of a pain initially, as Stonehearth claimed that his version did not match my [host] version until the third try of removing ACE entirely and adding it back on again.

We saved and took a small break, but when I came back to restart the game, supposedly my version of ACE did not match the Steam version?? We wound up removing and reinstalling ACE again and restarting a few times before he could join into my world again.

I just don't see how the clients could become incompatible with one another that quickly when we both had updated our files at the same time and started the world AFTER 0.9.5.7:f was released.
