Combined generals movement CTD

[Makanyane]

This one is going to take a bit to explain (and second question why am I spending half of Christmas Eve doing this!!!!), and happy seasonal stuff to everybody, anyway;

Reproducible from save CTD, three generals A, B, and C can reach city (ravenna) to beseige it although all have slightly different movement ranges. Any of them sent individually with or without army do not CTD. But general A seems to be problem, if A is sent with either B or C and given order to attack city from their initial starting position, (towards limit of movement) I get CTD when the generals (with or without army) reach city. However if same combination of generals / army are sent and given order to move to a position before city, stop there, and are then ordered to besiege city within same turn then there is no problem!

I've made some changes to traits etc. but nothing that should have directly effected movement, and none of the generals actually has a trait / ancillary that says it effects movement. Has anyone else seen anything like this?

Slightly confused, are the different movement ranges because some of them have already moved a bit? Otherwise it might be a clue.
