It's become a guessing game as to what has happened in Radeon Settings, whether my settings and profiles have vanished completely or if they've just been slightly altered.
Example, and what prompted me to post this: I've been running 1800 core and ~970 mV successfully for some time, but earlier I noticed temperatures creeping into unacceptable territory. I only now discovered why - WattMan decided the room needed some extra heat and upped the voltage to to 1200 mV, but kept the core at my setting of 1800. What? Why? Nothing crashed, it was all fine. Why would this change have been made? It makes no sense.
