Matrix spotting issue

[Huib Versloot]

I think an arty hit on rafts in water always, or nearly always destroys all units. As the crossing sites are not likely to be in LOS, there is still some luck involved for the arty landing on the hexes with the rafts and knowing when the Germans are actually on the river.
I'm cutting on the amount of Allied artillery in that scenario, even if this large amount was historical, the Germans had tunneled the river dikes so extensively that, apart from the crossings, they hardly suffered any casualties from Allied artillery fire.
