Another user discovered and reasoned out a glitch with Laecia & something RE: latest patch (pardon if these get to be too much!):
I figured out the Laecia glitch, sorta. I had to not save on chapter 13, otherwise it registered Laecia as already being in her transformed state, as opposed to going through the cutscene to transform her, and this seemed to bug out the game's understanding of the unit.
Also: having the MC class up before the gender choice causes you to revert back to sorceress if you pick female/futa and you can't re-class back up.
Patch 0.48 fix this problem for both Illyria and Laecia through the release of a new item (Class Badge 2).
Instead, 0.48 break the Item Shop forcing it to revert to "level 1" ignoring the current level of the store. If you try to upgrade again, both the "upgrade XXXX/YYY money/exp" (if you weren't level 3 already) and the "Progression Required" appear at the same time.
Tecnique also bug in the new patch, if you already maxed it at level 3 previously you can't upgrade it to level 4-5 in the new patch, the game recognize it as "full upgraded".
