I get that error when I register a pokemon to the pokedex. It doesnt crash the game but I don't get the pokemon. It gets registered and i get the pokemon if i catch another. I'm using 16.2

Can somebody help me?

Edit: I was able to fix this by creating a new project and putting only the stuff I needed from the old one into the new one.
