Interestingly enough, the next DoT does seem to behave normally... it ticks 6 times every time. So, could it be some specific spells? Throwing an hypothesis out there.

Experiencing the same with the Wizard earth spec single DoT. I have recorded some footage, I'd just need to quickly edit it. Would this be helpful? DoT ticks once, or sometimes twice. It should tick over 12 seconds, every 2 seconds. So... ticks at 0, 2, 4, 6, 8, 10, 12? https://i.postimg.cc/gr8xkPPH...
