Components, classes and even the styling vanishing suddenly, happening again and again.
Everything was working fine and reflecting on frontend. Suddenly styling vanished from frontend when I came back to builder, classes was not there, they had vanished. One of my component is also deleted. It has happened with me 10 of times.
It is happening again and again. No caching at all on site, its a dev site.
However, I was also not able to replicate it there. Do you have a special setup? Have you noticed any similarities between the cases when this happens?
You mentioned three things, which are all different:
Components beeing deleted (same as the topic above)
ID styling level vanishing
Classes being deleted
Do you have multiple tabs open? Maybe multiple users work on pages at once? Can you replicate this even with all plugins disabled?
