This has happened before in the past but never on this scale. After not touching my development website for 2 weeks, I logged in to edit my menu block and after publishing it with NO changes, everything was broken.
I have serious suspicions that when you change some blocks, our ALREADY existing blocks are also affected.
This is completely unacceptable. My backups also fail since when I hit publish the builder tries to apply the new block style over the old one I used, your page backup fails for the same reason and revisions fail for the same reason.
So in the end I have lost about a months work and 3 backup techniques fail due to your very broken block system.
Please tell me a way I can guarantee I don’t lose my work whenever you change things in your code, so I can complete this website and not use this software again.
