This happened on 2 occasions but only have video of one where when rolling and using the harvester a rocketjump can occur. This jump allows you to reach the map edge and could potentially be used to bypass areas. Kill walls are still active though when going too far to the edge.

(Onedrive link because video is too large, bug is at 0:15)
