Ok interesting, I'm pretty sure I fixed the inventory persistence bug. The problem was I had used buttons for the icons and set active/inactive images, and apparently those states don't get stored in saves. But the actual value that is checked to see which pendulum the player has was unaffected, it reverted back to 0 (no pendulum) like it should have when the autosave is loaded. So it seems like this is a different issue, I'll see if I can replicate what you are describing tonight and hopefully get it fixed.
