Not on mine, But it looks like you or someone that had it tightend that screw down to much. you can tell it was tightend by the looks of the screw, kinda scratced up from a screwdriver and a heavy hand. either that or it was dropped or slammed down.
I just put a piece of black tape over it, seems to be functioning just fine. Its never been dropped or tampered with, so I have no idea how the cracks happened.
Thank you to everyone who checked.
On a second note, I have a black Uwell Crown tank & pack of coils on the way. I've read nothing but great reviews about this Sub-ohm tank so I'm excited to try my hand at one!

That is exactly what I have been using. Both black Sigelei 150 TC and Uwell Crown. Be careful about losing O-rings out of your crown. I thought it was leaking but did not think much of it until I noticed the glass was not sitting tight, way to loose. I put in one of the big O-rings on the top of the tank where it seemed to be missing and so far so good.
What tc coil is there that starts as high as .3 ohms? Seems like it would be a kanthal build and that would not be good for the chip. Hence them saying you need nickel build for temp control. If it is nickel, what tank?
Here is the build below & it is a dual coil NiFe 52 ish alloy on a Royal Hunter set to 80 joules & 380°F (= aprox 500°F +/- actual). This build read .29 on the Sigelei after dry firing & worked great for a few days till res creeped to .3 & then it started to jump out of TC mode. Still worked great in W mode, but it got me wondering if .3Ω was some sort of cold TC mode threshold peculiar to the Sigelei. So far the same build with one less wrap is staying in TC mode, but I'll see what happens in a few days when the coil starts to get a little build up. http://www.steam-engine.org/coil.as...26&id=3.0479999999999996&ll=1.651&ws=0.009906
