[1.12][BUG] "Save Game" executes planned moves before saving
If you save a game right before executing your planned move, this is too late... The planned move will be executed implicitly before the game is actually saved. See the debug.err file at http://pastebin.com/Ltht7ZuJ. (I could provide the autosave before the season plus the manually saved game.)
The above problem may be related to the proximity of a city. I have noticed also that units may change their position in a saved game if they are close to a city. This does not matter much though since movements through the city are free.
