help please!! 3 out of 6 clearomizers' tips that I ordered last week melted. I diy my own liquid and I'm thinking it's the vanilla extract that I used in my liquid, because 3 of my clearomizers tips melted to a kind of black glue and then the whole clearomizers cracked and broke into a few pieces. I have never had any other problem with my own liquids before and it just happened to be new clearomizers with the vanilla extract (which was the first time I used it) so I'm not sure which is the culprit, either the liquid or a couple of faulty clearomizers. I appreciate your feed back
