For general testings, I have been using a high fuel value fuel, and in the latest update, when the burner mining drill levels up, the rest of the fuel value of the only fuel I added is completely lost, and goes back to being "out of fuel".
Additionally, the mining/assembling machine progress is lost as well, which means if the machine is updated, and doesn't change level as part of the update, then it will be stuck there forever.
