“There’s an issue with the [exalt] launcher uninstaller currently, and it will delete the entire directory/folder the launcher is installed in if you use it. If you have the game installed with the default file path it provides you (eg for Windows, it’ll be somewhere in Program Files in its own RotMG Exalt folder), this should not be an issue as it will just delete the Exalt folder. If you have the game installed anywhere else, in a directory that also contains other files you want to keep, DO NOT USE THE UNINSTALLER until there is a fix.”
Update: The current versions uninstaller (0.9.2) shouldn’t have this problem anymore, however the old one will still behave the same.
