This thread is pretty old, but I hope it's still fine that I'm posting, as I have a problem. Namely, the exact same problem as everyone else in this thread. I've triple checked and everything is correct, extension is there, added in the config, it loads after user logger, names are correct and exactly the same everywhere (even the script in the project), but it keeps giving me this error. Not sure what's wrong. I saw this working fine in Pokemon Remexos. :< Any developments on this that haven't been posted?
