While I obviously can't speak for Defiant Pharma, I can say that every TNE I've had without guaiacol has crashed at room temp for me. I keep my house in the low 60's most of the year, if not colder in winter, but I think crashing is common for TNE, even at higher room temps. I got a mug warmer to dissolve the crystals back into suspension, and after that I keep it stored in a baby wipe warmer to prevent it from crashing again. Works perfectly. The wipe warmer has three temperature settings, I keep it on the middle setting at 113°. Highest is 131°, don't remember the lowest temp, maybe 90-ish. I've since got a much nicer 3D printed tray to go in there, was using a kit bottom here
