You never get back your original prompt or image references when you go back to older generations. Serious issue, Firefly is nearly unusable in professional situations where it is important to pivot back. Nano Banana 2 (please add 2.1 btw).

You generate an image with uploaded references. NB2 for example.
You generate several more until it gets right.
You decide, “no, I need to go back to that other start frame I was working on before, I just noticed a detail.”
So you click on the “timeline” of previous generations to the one you would like to go back, historically. 
Result: no loading of original prompt, reference uploads are not there. Everything just sits on the latest.
Heck even creating this report, I wanted to go back and edit the “Describe your bug” and it did the same thing, wiped out the “Add more details AND the subject line, just reset it all”. Exactly same issue. 
Proper harnesses would keep historical prompts for each generation. 
Proper harnesses would actualy keep your uploads so you do not have to upload them over and over again because of how bad Firefly UX is. 
I use all of the tools, Higgsfield, Hailou, etc. Gotta get better at this. Have Opus 5.5 fix this overnight for us please 😂
