If you haven’t already heard, Twitch now let’s you choose a new name once every 60 days. https://blog.twitch.tv/the-hype-is-real-name-changes-are-here-c629c4697154?sf58352669=1#.qojq1b5b4
This is a great new change on Twitch, however because of the way Warp World was designed we used your Twitch name as a unique identifier to organize your settings and levels. We will be migrating over to the Twitch ID system in the next few days, but we wanted to give everyone a heads up here that if you do change your name on Twitch, you will lose your settings and level stats when you login next. To prevent that, you can just let us know what you changed your name to and we can update it so all that information comes back. Eventually this will all be automated but Twitch likes to announce features without a whole lot of heads up.
Let us know if you have any questions!
