General issues with gameplay

Have done the foot steps of giants mission twice now solo and co op but no achievement also on doing the last proving ground I cannot enter the final sector and have made numerous attempts any one any ideas on a solution to either issue ?

What platform - PC, PS4, or XB1?

Xbox 1 tried deleting profile no joy and hard reset as well my other thought was to install on my other Xbox and hope it will sync

Should be updating the save files unless you’re forcing the game to quit without saving and then not allowing time to sync.

The other thought is if you’ve been playing off-line that might screw up the cloud sync. If you’ve been disconnecting to avoid the hotfix, you’ll want to reconnect before you quit your session. ISTR some weirdness over off-line versus on-line saves with the XB1 before.
