what it looks like is happening to me is that that unit is in "auto-explore" mode while you are trying to move it manually as well. This is a failing on our part in that we aren't displaying to you properly that the unit is auto-exploring. Also after manually moving it should probably cancel explore mode anyways. I'll forward it on.

You would think, but no, it's off. I have had several games where this behavior happens. Also, I never use "explore".
But while we are on the subject, the "explore" button needs a better indication if it is on or off. Perhaps a green "halo" like the "Turn" button gets.
