I just recently bought a herakles tank and have been thoroughly enjoying it. Flavor and vapor production is awesome. I took it off and refilled the tank and went to screw it back on my kbox when i noticed it sitting weirdly at an angle. Didnt think much of it so i went to hit it and would not fire. I then pushed it and heard a click and saw that it was now straight and now it hits like nothin was ever wrong...what causes this odd tilting..? Anyone else have this problem..?
