Okay, I was having the same problem recently, about a month into owning my Paranormal. I found a solution for me, give it a try and see if it works for you.
1. Go into the Atty settings
2. Manually adjust the coil resistance to about .2 Ω lower or higher than the current measured resistance
3. Fire the mod a couple times
4. Go back to Atty settings
5. Manually or automatically change the coil resistance back to what it should be or what it is reading at room temp.
That should fix it for good until you change the coil again. I know it's annoying but hey, we're using Temp Control, we have it kind of easy not having to change cotton and coils as often as kanthal users. Until Evolv comes out with a patch for this, hopefully my solution can help you out.
