well, stop over tightening your mod, especially after chain vaping. Once everything is warm, metal expands, if you tighten things up when warm/hot, when it cools, yeah, she be stuck tight, don't matter if it copper, brass, ss, or gold, tis in the nature of metal.
Snug not tight, but no matter what, one will experience stuck gear, happens, try not to do it again, but, yeah, it will happen. A rag and some vise grips are handy to have also
