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.
