But wait, there was this post:
It’s that part where it says “seamlessly moved” is what I have reservations about judging from past major patches that created unintended problems, I guess I’m preparing a contingency plan in case something goes wrong in the transfer of my Aspects into the Codex in Eternal. Hopefully, my stored Aspects will indeed be “seemlessly moved” to my Codex but if not, and I kept an Aspect still in a legendary item, then I can still extract it and the Codex will update accordingly.
