When running a game session pulling from an alternate Game Directory, options.txt remains native to the original directory. Backtracking versions overrides current options.txt because certain parameters aren't present, then changing profiles back to future versions, the options are reset to default.
An options.txt is created in the separate directory, but not edited or used.

Is this still a concern in the current Minecraft Launcher version 2.0.805 / 2.0.806? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases. If this has been done, we can reopen the issue.

Unable to reproduce.
