What Toffer90 says it's not what happened to us. First of all, it only happened with naval units so far (well, it happened just once with a worker, but that was before I imported your latest changes into the dll of AND, so I think that part was solved). Second we did not interrupt a go-to order and reissued to the same destination. As I explained in the post above, the galley was 2 tiles north from that barbarian galley you see in the screenshot; my wife moved it 1 tile south, just north of the barbarian galley; it didn't stop its movement by itself: my wife stopped it there. Then she resumed moving her galley programming the galley to move 1 square south of the barbarian galley, where you can see it in the screenshot (2 tiles movement, 1SW and 1SE). That's when the OOS happened because her galley moved on her pc but not on mine (in fact I immediately saved the game and if we reload it, it looks like her galley hasn't moved and it's still 1 tile north of the barbarian galley). So no, it's not something related to moving the unit to the same destination after its moves have been interrupted.
