Okay I had a hell of a time just trying to get the damn pivot system to actually work
and information seems to be pretty scarce out there about this, but I eventually managed to figure it out thankfully.
Some back story, during the pivot tutorial the game informed me that it could not access the Ubisoft servers, and as a result I was unable to place any. After quitting the game, checking my connection and loading my save again, I found that I just was not able to access the pivot system.
Here is my broken Pivot screen - the pivot screen shows that there are 0 pivots to find and 0 to place (screenshot below). Looking at the three pivots you can search for, it says that their location is "Undefined"
Since then, I noticed that whilst being unable to access the pivot system, I couldn't view any of the leaderboards either (I was treated to a spinning circle that never gave results). Access to multiplayer, uPlay and such continue to function as normal. Attempts at a later date do not suddenly cause it to work (I waited four months of attempting on and off, no success). No amount of console reboots, reinstallations or new saves were causing the pivot system or the leader boards to ever work.
If you're experiencing the above issues, even when selecting a new game on a new save slot, before attempting to delete everything (which I very nearly did...), I found a number of methods across the net which cause it to start working again. Unfortunately I didn't find a specific fix, but I at least got it working once more. If someone with more patience wants to attempt each solution individually, then you're welcome to leave a comment below to help someone else.
- I logged in to a 360 Backwards Compatible game, or an Xbox 360, and reduced the number of friends on my friends list down to <40 - at least until I got this achievement out the way. I got mine to down to 19 as I was desperate, but I'm seeing around the 'net that anything more than 45 friends causes problems.
- As I play this on Xbox One via BC, again, I ensured that my friends list was <40.
- On a web browser, I visited the uPlay website and logged in to the uPlay account my gamertag is linked to. Through there, I unlinked every
account that my uPlay account was linked to (Facebook and Xbox Live).
- As I'm playing on Xbox One, I uninstalled the game, went into the system settings and selected the "Delete local Xbox 360 Storage" option. If you're playing on 360, then go into settings and clear the system cache.
After doing all of this, I installed and booted up AC3 again, then selected the uPlay option on the main menu to confirm that my account was 'unlinked'. It asked me to sign in or create an account, so this confirmed it. I then loaded my save and checked the leaderboards - suddenly working, and checked the Pivot system - also suddenly working. Relieved, I did all the pivots in one sitting (it's not very difficult and only takes about an hour if you've found all the fast travel points on the map).
I really hope this helps someone with a similar problem I really don't know if this solution will work for you, but it worked for me.
