Recently, while fighting on a frozen major river, the ground thawed (next turn), but the Armour was still on the Major river hex! Shouldn't those units been lost, for being in a non-occupiable hex for it's unit type!
Thanks

i guess, it JUST managed to reach the river bank in time ?

Yea I know, but which bank! Anybody now how the combat odds are figured when a unit is in a illegal hex? I should have looked but I thought that they where easy pickings, my mistake!
