So many things are going wrong with unit selection, grouping, and army formation that I don't even know how to tell the problems apart from each other. Before today's patch, I noticed a few things - but now it seems like a dozen.
If I have two groups, and in each group I have all of the units in an army, then later I select all of the units and try to reassign them to one group it doesn't work. some of the units change groups, but not all. Sometimes unis end up in two groups. If I disband the armies first, then regroup, it seems to work right.
Before the patch, sometimes all the units in a group would die, but the empty group would still appear on the HUD. But not always. I don't think I saw that yet today.
But now, I think I've seen cases where some units in an army in a group die, and all of the sudden the group is just gone. The units are still there, and rendered as if they were selected, but I think they're not actually selected. Groups are definitely vanishing, but I'm not completely sure why.
I just played a single player game, and a ranked 1v1, and it was a constant struggle to keep track of units because of groups disappearing. I also had major issues with hades bombers refusing to move. They just got stuck. Or weren't really selected. Or something. The commands were acknowledged, but nothing was happening. I felt like I had about 40% of the level of control over my units that I should have.
Also, once (a week or two ago) I hit a number hotkey to a group I had previously assigned, and the screen refocused onto my opponent's side of the map. Early game, I hadn't been anywhere near there yet. That was definitely a wtf moment.
Anyhow, please take a hard look at this, because it is very difficult to play right now.
