When I use the Get Assistant endpoint, I can see that the original prompt is still there, but the assistant is broken, as she ignores the original prompting and just says the original greeting and then goes silent... I was supposed to demo this assistant to somebody tomorrow, as it was basically complete, I was just trying to add the ability for her to check time/date via a custom tool. Is there a way to revert back to not using the "blocks" way of building the assistant?
