I think this improved the last couple of days to be honest, sometimes the problem was there, sometimes not. I got used to drafting prompt changes outside and copying them in for publish so I retained a good version outside. Tomorrow I'm teaching a colleague to make his own assistant, so we should be doing a lot of publishing and we can report back if we see the issue then.
I like the orange pen icon, was that new recently? I cant remember not having it now, but not sure 🙃
