The latter is ticking constantly. I can play the game with no apparent issues when I turn Auto-Open off, but is there something I can do to stop it? Or is that just a permanent feature of this save now?

Welcome at the testing of the unstable version.
Maybe the error get fixed with a new release, but maybe not.
You should just wait for the new patch.
