There was a serious bug in GPU version: https://github.com/SChernykh/Amicable/commit/3470ed855d244100f37b0b7ab4c912d2b9365a93
Unfortunately, it skipped some numbers in an unpredictable way for "large primes" work units for the last 20 days 9 days. I'll have to reissue all such work units to cover everything missed. The GPU versions for all platforms are already updated.

Sorry for the mess, but it's good that the bug is fixed relatively early, because it was hard to notice.

Well, I'm glad this was caught early! 20 days is a lot better than 200 days :)

Is this bug the reason for the semi-random work unit runtimes lately?

Yes, it was running random percentage of a work unit instead of full 100%.

Good news: I was able to narrow down the invalid work units range to only last 9 days after further analysis of this bug.
