Hi! It seems Schallfalke hasn't been active for some months, so I've updated my mod. :-)
It should find all trees. Are stromatholites the only kind of rock that isn't recognized? Haven't handled them yet. But trees and rocks are mined now, so you should get whatever mining products they leave.
Also, if a vehicle has both driver and passenger (both players), we will now try to give items to the driver first. Remaining items are then given to the passenger, and anything remaining after that is spilled on the ground. Autodrive (and any other mods that care) will have a chance to remove items for the refueling. This will only work if the vehicle has a fuel sensor, and has fuel preferences set. (To set fuel-prefs, open the GUI, modify items or amounts, then close the GUI to confirm the changes!)
