gv meeting more then 2 planes rolling

[WiLdStar5]

what i have noticed is when a gv meets more then 2 planes at the same time they roll and dont stop rolling without doing an alt-f4... so your comming to a hill that has on side to your left and one to the right and the plane your on... when you hit the 3 planes in the spot where they come together the gv roll and then sound like thier going faster and faster down hill and you dont stop rolling without doing alt f4

I've noticed this as well, at the bottom of hills where there is a v-shape, on hitting that spot where the three "planes" intersect, the gv begins rolling.
