Fatal error: Detected non-empty blocksets with no associated blocks

It doesn’t look like you reported details, to try to figure out what’s going on. Care to here, or in new topic?
Things possibly are a little better in 2.0.5.1 (what are you on?) compared to what existed at time of topic. There are still issues (I think) with things like hard stops. Canary has some fixes, but is still not perfect…
Someone who gets this constantly is ideal help for trying to isolate the problem, which is what’s needed.
