I'll have to look into this but my first guess is the game is very confused. It thinks it's fighting a meeting engagement but it's found a map with the river assault flags set and has generated the rafts.

The game was not originally designed to allow personalized maps in campaigns. We added that ability so players could create and fight on their own maps but specialty maps like river or beach assault maps can cause problems as you've discovered and should be avoided
