Hello,
Im having trouble pinpointing a bug with regards to unit grouping.
Sometimes when you do your turn, you will notice it is not possible to unmark a (follower) unit from a group by clicking on this unit - unless you use the button "select/unselect all units" etc.
If this happens in a game, please do not move or ungroup this stack with the button - but rather report it to me in the bugforum (gamename/gameid an which stack this is), and I can investigate this and hopefully find the source of this annoying bug
Thanks!
