Was supposed to come out Sept 2020
I'm not trying to willfully find issues, but I come across issues all the time. I'm in various gear groups and forums for all the major modelers, and nothing else pops up with the catastrophic issues the QC has with any sort of frequency the QC has.
Try to willfully find and propagate issues for other modelers, see what you can come up with... I bet it's not weekly reports of catastrophic failures.
No user-known issues, but there could be, who knows. I wonder if a lot of these catastrophic failures are still due to the SD card. Maybe it's getting loose or losing connection despite the little holder they affixed in later revisions, or maybe just using prone-to-corrupt memory, etc.
