After using a shift key to open the gold chest in sanctuary other games on my system suffer performance issues. The problem gets resolved after I rebuild the database. Is this where I report this?
That is truly weird. Is your hard drive tight on free space at all? Using a key would require a couple of files to be updated, which presumably means a temp file being created then deleted along the way. None of them should be that big though - does the PS4 let you see how big your game saves and profile.sav file are for BL3?
