Yeah, all that and.. since I own a Rx200 I can tell you this.. when you take off your tank or RDA, is the bottom of the plate wet? Is there a little juice down in the 510? When mine 'overflow' a little or leak around the o-rings or whatever, I wind up with a little bit of juice under the adapter and what is happening is that this moisture is creating a short between the two posts and all the threads and the RX is just saying 'Uh, Uh, bro.. no way I'm firing like that.' I used to unscrew a little and screw back down and that would get it going but the worse it got, the more liquid was down there so I imagine you're probably having a little bit of both going on. Don't be mad at it tho.. better that than battery burns.. :/
