We "professional" beta testers make a distinction between a bug and an anomaly. (More than two decades of testing with premier co.'s, under very restrictive NDA's...avocationally.) So...I have had what I am counting an anomaly 'cause it's happened only once..so far. (A bug must be replicable by definition.)
Vaping on a tank on and off for about two hours, while watching videos, I had an effect like drying wick on a TP build. Turned the tank upside down seeing there's plenty of eliquid available. Vaping...vaping...vaping, I get that sense again a while later, running out of liquid? Not according to what I see.
Eventually, I look at the screen of the VS rDNA, not believing my eyes I go back to vaping. Shortly I get a repeat of the above behavior but this time I do believe my eyes. Where the display should show (degrees) "F" it show "V". At the resistance line I notice that a build that was 0.18 (or 0.20, two different R91's so I don't remember which was atop) now reads 0.35 or 0.37. The tank's base is warmer than usual.
Not enough information to form a hypothesis, yet, I believe the additional heat may have convinced the board that I had switched to a Kanthal build. What is missing from by scenario is that I do not remember whether I removed the tank to check the liquid level. So, my possible hypothesis does not rise above the level of pure speculation.
Nevertheless, I have accurately reported my "experience".
