I have now had 3 Gas Canisters disappear from my inventory when attached to a gas stove, as well as a Skillet. The first two instances I only had a gas can attached to the gas stove and they remained attached while in game, however when I logged back in to the game next the gas stoves had disappeared (separate occasions). The most recent instance I had attached a gas can and a skillet to my gas stove, and same problem...after I logged out and back on, both attachments were missing.
