On the point of version control, that’s a huge part of the problem with this bug; once events lose association in the sequence, reverting to previous revisions does nothing to help, the event timeline is broken and as far as we’ve been told by epic staff, there’s nothing we can do to fix them once that’s happened.
I’m glad you’re not affected by this issue, but sequencer is not “one of thousands of features”, it’s a major engine system composed of many features, and for teams that DO use sequencer (which is many if not most), a bug that can permanently dissociate your assets is a big deal.
