On Xbox One the save system doesn't work correctly for me. I've been playing 15 hours and had several issues with syncing the save file. This results in:
1) not being able to start ('continue') the game (it's greyed out in the startmenu)
2) in game saving (quick or regular) not possible and losing hours of progress.

Currently very annoyed with this. I want to like the game but it's clumsy inventorymanagement and broken savesystem really make it hard to enjoy for me.
