Wait are you sure? I think the entry crash has something to do with the images in my Pictures folder. Because even as I start a new save file the game still crashes, regardless if i add new Pokemon or not.
Nevermind, I'm pretty sure you're right. I tried using an old save after adding 1 new species and it wasnt working. Dammit I really wanted it to be like a normal game, where every big update I add a new character (in this case a new Pokemon) but I guess that can't happen.
I'm so sorry for not knowing that btw, I'm just really new to essentials. But adding new forms to Pokemon shouldn't ruin the save files right? Like not an entire species, just another form.
