I have a party of 3 wandering pack drakes on my map. When I click anywhere on the surrounding tiles, for whatever reason (selection or order) they are seen my the game as the target, unless for maybe a quarter of the furthest part of them, if I search for it. So I found myself accidentally attacking them, or having difficulties to select a unit on the tile next to it (that nowhere near powerful enough to take it out). It's the only time I got such a problem, the other creatures I found don't do that.
Moreover, it seems to trigger the bug where the target point of the mouse cursor changes.
