Filling 2L tank with 20L jerrycan empties the jerrycan

Version 5062, tiled, Windows 7.

The last mention of this in the forum was 2013. Sorry if I missed a more recent message.

I had a 23% full jerrycan (~5L of gasoline, 13800 units) and I 'U’nloaded it into a vehicle with a “gasoline tank (little)” (2L). I received a message saying “You refill the Cooker with gasoline to its maximum.” However, my jerrycan is now empty.

There is only one gas tank on my wooden-framed minifridge-kitchen-chemlab thingus and there were no pools of gasoline after I emptied it.

Please let me know if you require any further information.

Thanks,
Richard
