Far Cry 4 PC Patch 1.6.0 Introduces Major Save Glitch
 

It would seem that the latest patch for the PC version of Far Cry 4 introduces a major save glitch. Shacknews has the complete rundown, including word from the developer on a fix. Users on both the Far Cry 4 forums and our own Chatty community have observed that the crash occurs when your character is at Karma level 8. Upon reaching this level, autosave will not function and attempting to save manually will lead to a freeze.
