I'm not seeing any issues. Precht was the one who put Mavis in the crystal, and he experimented with a lot of different magics in the process of learning how to revive her, so it stands to reason that he knew ways to take the baby out without freeing Mavis. I was under the impression that that didn't need to be explained. As for retcons, retcons are when you replace existing knowledge with new knowledge on the same subject to create a change in, usually, inconsistency. What we have right now are unexplained, strange occurrences. What happens next may be a retcon, but no retcons have taken place yet, lol. We have to wait for the explanations to see if there are retcons. What these are, are plot holes. Big difference, guys.
