I don't have any experience with the twisp so not sure about the coils. Do you by any chance have another clearo you could try?
Peppery sounds to me like the wick inside the coil might of burnt. Happens to me all the time with my protank. I just remove it, soak in vodka and dry burn it. Obviously this isn't an easy option if you only have 1 clearo. Luckily with the kanger tanks, a spare coil is only R30 so I have plenty.
I know it is a different story with Twisp though
