we are playing a 3 player tcp-ip lan game,none of us can see any designs we have made in a single player game in multiplayer,it not the end of the world just annoying.
I haven't had the opportunity to play a TCP/IP game, so there may very well be a bug. I'll have to try setting one up to see if I can replicate your results. If so, we can send a bug report to Aaron (Malfador).
