UBI never addressed the famous 88% bug that affects PC and consoles, if you not aware what it is go check ubi forums and you will see a huge thread on this that started back when game came out. There are issues with the dynamic mission path in the game that causes many players get stuck at 88% when they cannot enter door to a bar. Some people came up with workaround on a console using mortar glitch to clip through the wall. Now thats what you call "user fix" rofl.
