After testing out the Portable Stove in .48 I noticed that if you place the Stove on the ground and then turn it on it will make the "hissing" sound of gas until the server restarts even if you turn the stove off and/or pick it up. You can leave the server and come back and still hear the hiss. I'm guessing it goes away after the server restarts but it might still be hissing even after restart.
