In my recent game, my duplicants are in space using jet suits, and are constantly flying off the side of the map, only to return a few seconds later carrying dirt. I'm unsure why there's resources for them to pick up off the side of the map, or why pathfinding will allow them to go that far.
Steps to Reproduce
With jet suits in space, duplicants will happily fly off the map to pick up out of bounds resources.
This issue has been fixed in either a future version or updated in a previous version.
