[Bug 1846423]

[Bugzilla-m]

I think, wasting time dealing with undeletable reminders is an inconvenience nobody needs.
To get rid of this, you need to downgrade on a backup, naturally always losing changes made since then.
Exporting the buggy bunch and reimporting it into a clean installation results in the same error.
Editing doesn't help.
After weeks I decided to go through by hand an restore what I could out of my analogue backup.
So, I take this bug serious.
Nobody in charge seems to.
This doesn't speak for bugzilla.
Or *does* it?
