If I opt in for the Public Test Branch that is available now, will I lose any progress done in that test branch? Will I keep anything I do on that even when the official update is released with that content?

I dont mind runing on a test version to help with bug fixes but I definitely dont want to lose my save progress.

Thanks,

The savegames made in the public test branch might not work back on a non test version. There is not that much to do in the current test branch progress wise though.
