Thanks for sharing all those details! I checked the latest info, and as of January 29, 2025, the 'Say' and 'Gather' nodes should still be available in Vapi workflows, with some recent improvements ([changelog](
https://docs.vapi.ai/changelog/2025/1/29)). However, I couldn't find anything about why they might be missing from your editor or how to access your old workflow. I'm escalating this to our team so a human can take a closer look and help you out!
