There is a big bug with the XB and the workshop installs. It doesn't uninstall any downloaded items from th rreserved sorage on the console, if we unsubsribe the item in the workshop. The items gets deleted in the Workshop, but not in the local console storage. So the free memory gets filled and filled and never gets cleared. I have not found a way to delete any installed items localy on the console. So at some point my complete 1 GB Storage gets filled. The only solution would be to delete der "Reserver Storage" in the XB Applicaitons System data settings. This will clear the memeore but I will loose all my workshop dowloads.
