I've already reported a bug on the heavy rover, but this time I'm reporting it after testing it on both crusher under different conditions. When I position the rover on the shredder's ramp (small or large, it's the same), in third-person view, a sign appears indicating that I'm in an unloading zone. But in first-person view, the vehicle doesn't react. Aside from that, I can operate the shredder with the pickup or manually without any issues.
After several tests, I think that trying to move the trailer arm on the crusher's ramp displays an error message that seems to permanently disable the vehicle's unloading interface. (Test performed with a brand new rover)
