Hi kayylth, the unit count is best to look at at the start of your turn. At this time it will have the correct number of troops. If you buy units, the number will go up. The numbers for the other players will remain the same regardless if they buy troops and will stay the same until the start of the next turn. As far as I'm aware, the unit count does include stealth. As for your question regarding those glitches, it does occur at times, but normally, at least for me, it is cleared up the next turn.
