It is as it is, bad luck, I have only one base left with the old llr 3.8.21, all other are running now with llr2 and a Gerbicz check which detects bad hardware and rerunning from the last check point. We have already planned some double checks, one is running at the moment. 
Standalone, these last two bases for n=100k300k are not extremely unusual. Taken as a whole for the year of 2022, what has happened is extraordinary. We had ~2025 bases with 2 k's remaining, all of which had no primes for either n=300k500k or 400k500k followed up by R88 with 0 out of 19 for n=250k500k.
After the above, there were some bases with a normal # of primes, and then we had these two for n=100k300k: R711: Sieve depth: 1e15 # of tests: 71198 expected # of primes: 3.7 actual # of primes: 1 S954: Sieve depth: 1e15 # of tests: 60181 expected # of primes: 3.0 actual # of primes: 2 (k=119 had both primes) By themselves, nothing to be alarmed about. It's just become a recurring theme this year. What sticks out at me the most about R711 is that there were 8 primes for n=50k100k but only 1 prime for n=100k300k. This happens often on the project due to sheer randomness but it's just been strangely frequent recently.
