Another thing spotted last night-- built my port in Osumi and found that the map acts as though the port is in the other sea region to the one where it shows on the map. This is the case for trade and shipping out troops and agents.

I find that armies tend to hide behind castles on the camp map, too. I think this may be down to origin co-ordinates, but I may be wrong. Perhaps the castles could be reduced in size, so that they're not big enough to conceal a whole stack?

Meanwhile my empire is growing, having a few good battles, trade is beginning to get into gear now and my Daimyo is maxxed out on influence. Haven't teched up for all troop types yet, but when I have I'll start testing the retraining issues from beta5/6, but can't imagine there'll be any problems now SP & MP units have been split.
