1. Loaded a song
2. Changed the loop in Simpler
3. some actions later -> "sample is offline" in Simpler.
4. Reloading song -> "cannot show waveform"
5. Restarting Live -> back to normal

If it’s something you can reproduce, best to report to https://www.ableton.com/en/help/#contact-support.

EYE should reproduce it... ok.

I mean what the state of the software is one can clearly see when selecting/deselecting all favorites. How can it happen that setting a flag in all objects of a list cannot be reliably set?

This feature is years old, often used and is left over just like that. I would be ashamed!
