Hey Sindweller!
Thanks for bringing that to my attention! Based on your in-depth description (thank you btw, more info than less in these situations are priceless) I know whats happening. Unlike the Instructor Memories, the Alchemist ones carry over into new games. However, the Memory screen doesn't give you access, until you make a new memory, so that should be why you unlocking the Alchemist memories alongside the Archery one. If that doesn't sound right though, let me know and I can look further into it.
I know its odd only hers carry over, but the memories were actually a very last minute addition to extended demo and I was testing how to carry over stats. Full game gallery will be more refined and all images will carry over. Cheers! -din
It's funny that you mention the memories carrying over into new games because just right before this playthrough I downloaded the latest version of the Extended Demo and deleted all the previous files, including saves, altogether. So it's definitely something different. Honestly, I believe it's not something game breaking and you probably have more important things to do, so I just thought that I would bring it to your attention :)
