I've been working on breeding some Vulpaphylas lately and after the update there are a few bugs that have popped up sometimes.
There are multiple bugs:
1) The Genetic Tools menu sometimes disappears entirely, depending on your currently equipped pet (equipping a not-yet-gilded animal seems to only -sometimes- be the cause).
2) The Genetic Tools new submenu for selecting which animal to imprint, does not always show the correct appearance of an animal when clicked on. The animal's size will change correctly but the antigen/mutagen effected appearance and breed traits will not always update between animals that have different appearances like it should.
3) The Genetic Tools menu will sometimes allow you to create a Genetic Imprint of NON-GILDED animals. When you go to the new submenu for selecting which animal to imprint, NON-GILDED animals are available for selection, and selecting them DOES WORK.
4) The Genetic Tools menu will sometimes NOT allow you to create a Genetic Imprint of GILDED animals. It will go to the new submenu for selecting which animal to imprint, but upon selecting a Gilded animal it may throw up an error message reading "Cannot make imprints of pets when they have not yet matured. Mature to an adult before creating imprint." despite the animal already being an adult and Gilded. Regressing and maturing the animal does not stop this error message from popping up, meaning imprints of the animal CANNOT be made.
