I changed the game version on steam to the PTS to try it out, and opened my main save file on the PTS. None of the new stuff showed up, so I gave up and reverted back to the regular version of the game. When I opened it, I got a warning that says "Current version of the game is not compatible with your saves.... update the game to the latest version." and my save is not available to be loaded.
I have the .cfg of my main save, and it opens fine on the PTS version, so is there a way to revert it back to normal? Do I have to wait until the update comes out so I can use it again? Will even that work? I think the steam version of PTS is pretty dangerous if opening my save makes it unplayable, and it should probably be a different application you launch on steam instead of a beta version.
