Issue description
Rock piles up in a vertical wall at the edge of the map

The short side of the screenshot is freshly filled. Not much dumped there
The long side i dump for millennials and suddenly it doesnt roll into the void
As i see it only happens when dumped with trucks because the top most stackers run forever
In this area wasnt dumped for about 6 hours and the piles of the stackers disappeared like normal
