Why 9.1? Because there's only one fix in this update Removed the checks for the key in the hook which should remove the 'E' bug while allowing prop protection. This means that food etc can be stolen now also. Food can be stolen. Don't comment on two things, it really is just one change.
But that's two... Checking if the player actually owned something was the cause of the E bug, so Teddi just removed it, also causing food to be able to be stolen
