There seem to be a few big problems.
1. Any time the players fight it seems to make things unusually unstable, 6/10 times my game lagged out it was fighting over the princess
2. the other 4/10 times the magic seems to overload it to the point of lagging out, especially when the industrialist goes at it, telling everyone to stop moving and stop casting TENDS to stop the lag and allow the game to continue, but I've had one occassion where that failed
3. Due to the 2 above things, along with the inherent things above, few games of more than 2 people last long before being lagged out, which kinda sucks since the premise is to get 4 people together to duel it out.
4. Me and a bunch of my other friends are having this bug occur, where occassionally if we join someone elses game, all our weapons and animals get deleted... we can't use any of them anymore. I don't know why or how this happens, but it's VERY bad, as I almost finally had everything and then in one fell swoop it was all gone. It tends to happen after a game has lagged out or someone is kicked during a level.
I don't very well know how you could address the first 3 problems, but the last one is something you should be able to prevent. PLEASE patch this amazing game, if you can make multiplayer not lag out so quickly, that's wonderful, but at very least find a way to make it so we don't lose all our weapons and animals :(
