Whyn get rid of Spirit Evolution?

[Threshield]

So while I could complain about stuff like how Wings, Decals, and such are storage transferable the game has always been like that and I have learned to accept it. My Problem is that they got rid of Evolution Spirts on this patch, I was pretty Excited when I got the Iona spirit since I saw it online, after getting three I was fine because Whatever He is an evolution spirit but they took it out with patch. The worse thing is anyone who Evolved their Spirit prior had them delevel I dont get why they dont get rid of it.

it's a known bug, and even more known that it shouldve been fixed by now. we players cant do anything about it.

Because Digimon trademarked it.
