Describe the bug

Game crashes when trying to proceed to the next turn, due to a scheduled movement of an escorted pair of units (Great General and Mechanized Infantry).

Steps to Reproduce

1. Load save attached below and proceed to next turn (crash).
2. Reload and find the only unit with a "Moving" action (last Mechanized Infantry unit).
3. Either break the escort or cancel the move to prevent the crash.

Additional Information

After encountering the crash scenario (post-win state), I narrowed down the problematic movement orders until only one unit remained and still triggered the crash.

The only noteworthy hints might be that I remember linking and unlinking the pair of units multiple times in the preceeding turn(s), possibly while embarked. Also, I noticed that the "Moving" action is listed with only one of the units (not sure if it's intentional).

Ooooh, that's an annoying bug. I see what the problem is now.
The mechanized infantry along with the great general are trying to reach the destination (-31, -13). Both of them try and find their own path to the tile to move to this turn (-30, -13). However, because the mechanized infantry has 3 movement and is directing the movement it can move through the hill at (-29, -13) with no problem. The great general on the other hand moves there and uses up all of it's movement so it can't move to (-30, -13) when the mechanized infantry wants to, so it raises an error.

Now to try and work out a fix...

For a report on this bug, I did try out a solution but encountered some serious errors on the way. I would estimate that fixing this would take a lot of time which I don't currently have. Considering that the AI doesn't use it, most players probably won't encounter this and that players can keep on playing by unlinking the units, I am going to be putting it on a low priority. I'll see when I have time to look into it farther.

Thanks for reporting this though!
