I’m just looking for any ideas on how to debug this. I don’t see how it would be a bbPress problem, but on the BuddyPress forum they basically said “Ask bbPress and GeneratePress.” So I’m doing that.

WordPress 5.9.2, BuddyPress 10.1.0, bbPress 2.6.9
(I haven’t upgraded to BP 10.2.0 yet, but I don’t see any fixes that seems to apply to this.)
It happens “once in a while” since upgrading to BP 10.1.0. (Four times since March 9th.)
It *might* be related to email notifications (mentions?) in a bbPress closed topic.
