They should be rare as hen's teeth.

Go back to a save game a turn or so before the end (if you have one) and restart that and you should be lucky.

However - if that also generates a river crossing then there may be a bug of the flag being carried over and not cleared, once you have had such a battle. If so - that would be handy to know (and I'll want a copy of your save game for debugging once we get back into things).

If it is a bug with the river flag not being cleared then you'll need to go back to a save-game before the present game started - and exit any river crossing game if offered in future, till I fix the revealed buglet. If no save - then a campaign restart I'm afraid.
