Alexei Zinoviev from Topcon reported the following reason for this R12
GLONASS tracking problem:

Currently, R12 broadcasts anomalous pseudorange measurements (it looks
like time scale of this satellite is shifted for one second with
respect to correct time). Due to additional checks in Net-G3 receivers,
such anomalous measurements are not available for recording and output.
As soon as this problem will be corrected by GLONASS Ground Segment,
Net-G3 receivers should start outputting GLONASS observables for R12.
