Bug Description
The promt "I want to reinstall my linux with a fresh image. I want first to copy everything I need from here and I want to know that my new arch linux will be useful and plug and play" was flagged as risk in Opus 5 and downgraded to Opus 4.8. This is really strange, something to investigate
