Status update! Mike replied right away, offering me two options for my replacement: Get another Indica now - caveat being that it might have the same issue as my previous two - or wait an estimated 2-3 weeks for a new model that shouldn't have any heating problems.
The herb addict in me is screaming "GET IT NOW, ME WANTS SMOKEY!!" but it's probably best to wait. In the meantime, I'll be purchasing an e-nano as my first desktop vape; hopefully that will arrive soon and tide me over until I can get the replacement Indica. Will report back in a few weeks, hopefully with the replacement in hand
