Hello! Looks like one of my utility scripts accidentally slipped into the Unity package, sorry for that. You're gonna want to go to the LeaderboardCreator/Utils path and delete the Clipboard script.
I've updated it now, and alternatively you can delete the LeaderboardCreator folder, download this new version of the package and import it.
Hey, thanks for the response. About the leaderboards disappearing from the list, they are only saved as cache, so as soon as you clear the data of websites on your browser, they will be gone. That is why it is important to save the secret keys.
I think that I could create an account system in the future, which would just require logging in, and your leaderboards will be accessible at any time, from any device without restoring all of them.
Well, it's me again :D
I'm getting a "A Native Collection has not been disposed, resulting in a memory leak. Enable Full StackTraces to get more details." (enabling Full stack trace doesn't give me any more info). I'm thinking it might have something to do with leaderboard creator since it only shows up after I scroll through my levels enough number of times, displaying the rankings for each as I scroll through. This discussion is talking about the same error and pointing to webRequests. I have no idea what that's about, really, but afaik, this is the only plugin I use that has it.
