I got my first “sorry I can’t do this” on Grok

I came to Grok from ChatGPT and was quite happy at how it never threw me “Sorry I can’t do this” bullshit in chat no matter what the role play was.

However today I tried to do a scene with sedation involved and suddenly it started giving me that same BS chatgpt gave! “I’m sorry I can’t do this”

Is this something new that came with the updates?
