Okay so i got a nautilus in the mail the other day, new head in it, primed it did all the prep with a new tank. Thing worked like a champ. Then last noght, after using it for 3 days i began to get a funny taste from the nautilus. It wasnt burnt just off. I checked it was whicking fine plenty of smoke just an off taste, so i go to use it this morning and it was completely burnt. Great thats fine, i brush it off as a dud. So i then put in a 1.8 ohm replacement head, prime it all that good stuff. It taste just perfect nothing wrong with it. Okay dont ask me how but later on i accidentally sat on the tank, i know stupid. So i unscrewed the bottom and the head was now at an angle screwed in. So after some force i unscrewed it, it looked fine no problems with it so i screwed it back in. That same funny taste is back. What should i do? This is my last head and i was trying to make these last. Also keep in mind I've been vaping at 3.2-3.6 volts. Nothing high.
