I haven't gotten any unknown errors, just the direct X error. It's so inconsistent, could be right when I log in, or hours in, none one day, then 5 errors in another. Mine were occurring in Shadowbringers, though they've definitely come back with a vengeance in the last week. It's good to know it's not a fault on our devices and seems to be an issue with FFXIV. I just wish it could be fixed so we can all enjoy FFXIV as much as we want! \o/
