I *never* experience this issue with RAIL movement but it does very often happen here with the move-by-river movement option.
If for example i move a stack from SC to KY via river and then deselect the move-by-river, the ghost stack disappears from destination region and all the path is cancelled. Doesn't happen here with rail but with river movement. (engine not converting river to standard march and cancels the whole move)
I "mechanized" this problem, after moving, if i cancel, i am still with the map on the destination but the stack i'd moved is still on the tabs. Just drag and drop it again, you don't need to look again for it
