World originally created in snapshot (a few versions ago).
Player was in Nether/Survival/cheats on first 1.7.5 load; missing all inventory and contents of chest nearby.
Changed to creative; verified all other chests in nether are empty. Used portal back to overworld; first opened chest verified empty; all further chests (and second time opening first chest) contents present and correct. Still missing all inventory, including armor.

Would going from a snapshot to a release be an upgrade?

@Ryandor - yes because 1.7.5 is just activaiting certain features that are present in the snapshot. The snapshot though is still newer (in version) than 1.7.5

Downgrading is not, was never and will never be officially supported.
This will not get fixed at any point.
