Silent 10MB upload failures from ownership bug

I run a small MSP with several clients that I convinced to use Nextcloud. Last year or so we got hit by the ownership transfer bug that broke moves and uploads over 10MB to shared and group folders.

It happened almost to the hour of our storage provider’s maintenance window, so I initially blamed it on that. It took two weeks for one client to report it, then another confirmed it a bit later. No user-facing errors — things just silently failed — and by then the affected version had been pulled.

We test uploads after updates of course, but I didn’t know Group Folders handles ownership transfers. I’m still a bit cut up and upset about it. Do you think I’m being too hard on myself?

It would be great if there were in-app notices for serious issues.
