@Trizek-WMF - thx for reporting the issue! There were some discrepancies before between the mentor status and the number of mentees assigned ( e.g. the selected settings wouldn't stick, not possible to select some specific combination of settings etc).
I'm checking it in testwiki (and in betalabs and will provide updates to this ticket as soon as possible.

Very good catch, @Trizek-WMF! This is an interesting bug. It can be reproduced "on demand" by first setting your mentorship state to "Away" and then running new mw.Api().saveOption('growthexperiments-mentor-away-timestamp', '20210101000000') in the console (any date in the past should work).

This can be reasonably fixed with the T347157: Structured mentor list: Migrate `autoAssigned` into weight maintenance piece of work. I think we should do both :)).

Although there is already a patch (thx, @Urbanecm_WMF!), I am adding here a confirmed current behavior on`testwiki wmf.27` and betalabs - the status Away is successfully changed back Active after a time interval set by a mentor is done. Number of mentees assigned to me falls to "None (I claim them manually)", disregarding the settings before Away status was set.

Hi @KStoller-WMF, I think T347436 is a separate bug, not a dupe of this
task. In this task, the issue happens when a mentor *returns* (their weight
is changed to None). In the other task, the issue happens when an admin
makes another mentor away until a date that's in the past (the save will be
"successful", but nothing would happen). I'd say the other task is a less
significant bug, as it doesn't seem to be breaking something, while this
task should be finished ASAP.

Thanks for the explanation! I've re-opened T347436.
