Getting and staying connected to the PC NA servers has been a bit of an issue today. No idea why and not pointing any fingers here because my ISP has been particularly flaky today, too. I logged out with a character around 2pm (local time) and was unable to log in with another for some reason. Not huge deal because I had guests coming over and needed to get the grill going anyway; it just delayed a couple of sets of daily crafting writs which weren't going to disappear until server reset. Guests came, grill cooked, food and beverages were consumed, and a good time was had by all. Then I came back to do those writs about four or five hours later. When trying to log in with the next character, I was presented with the message that my account was already logged in. Regardless of the truth condition of the error message, no reading of that error message looks good for ZOS.
If true, then it means that the character who logged out around 2pm (local time) was still logged in. Keep in mind that I couldn't connect to log in a different character, so I went off to do grilling instead, and apparently remained logged in for those four or five hours while a good time was being had with other activities. Remember that I'm assuming the "true" condition, not that it's actually the case.
If false, then it means that the game just flat out lied to me. There is no assumption which can mitigate a false statement. If it's false, then that's just a bald-faced lie.
If the game threw out something as an attempt to explain a failure to connect without having proper truth conditions to generate the message, then that is also not a good look. I'd refer you to the late Harry Frankfurter's treatise "On BS" (let's keep it G or PG). It's a very worthwhile read, but the thumbnail version is that a statement is BS when it is made without regard to its truth or falsity but only with regard to its effect on the statement's audience.The liar at least has some regard for the truth because the lie attempts to conceal it, but the BS'er uses whatever gets them the desired effect from the audience.
So which is it: truth (logged in for 4+ hours), lie, or BS? I had nothing but an easily replace food buff running on the character who logged out at 2, so there is no horrendously bad effect if the error message were true (unlike the prior character who logged out with a ticking 150% XP buff and 100% wayshrine discounts which still had about 50 minutes to run). But I can guarantee that you're not gaining that desired player trust with lies or BS.
I'm fresh out of outrage, but I could muster up some amused annoyance if required.
