So I just needed to vent. I'm creating a software simulation using screen recordings. I have several scenes, and am doing a Try Mode and a Test Mode. Lots of trigger edits in order to make the simulation behave like the live product, as well as branding considerations. I'm 80% finished, and was about to insert one of my screen recordings in Test mode, and I couldn't find it. I reviewed each of the screen recordings twice, spent about 2 hours trying to figure out what had happened. Then it dawned on me. That particular Try scene was created from screen shots, not a screen recording. It was added after the original screen recordings were made, and from a time and travel perspective, made more sense.
Moral of the story - take better notes.
Any Oooops moments anyone else wants to share?
