- when you go to drag a new unit to the map, you cannot "grab" it. You hear the click and the unit highlights, but no matter where you try to grab it, it does not move. If you keep trying different units at different locations, eventually the ability will be restored.
- when you are moving a unit, and you grab the unit in the unit box, as soon as your curosr is out of the unit area and on the map , the map begins to move as if you are draging the map. End result is that you cannot actually place the unit where you wanted.
edit: It just happen again and one led to the other. I tried to move a unit in the unit box, I grabbed it but as soon as the cursor got into the map area, the map began to move. I move the unit back to the unit box area. I then tried to grab it again, however, I started having the first problem above where I could not grab it. Not sure if this is always related, but will make an effort to note it when it happens.
