I turned 399 at 9am UTC which is the same time of day I bought my LTS so I'm guessing if I logegd in now I'd have the accolade as I'm guessing STO says which day you are playing (400) whereas the STO site says how many days you had been subscribed for (399).
I'm so confused though how some have got it when dStahl himself has said there shouldn't be, maybe there was a bug which meant it was live when it shouldn't have?
So I guess that confirms they did not count my time before I bought my LTS.
This would be correct. You would not receive credit until you had been charged for a subscription. The only way to do that before release was to buy an LTS. All of the other ones went active and started counting after the 30-day free period which was about march 4. If you bought an LTS anytime before then, then that is the day it should've went active and when it started counting.
It's really not that hard to figure out. For paying early for our subs (for a game that was not even released yet), we got credit for the subscription, while everyone else got additional time to play the game for free. I don't understand why some people feel screwed out of something that they will get eventually.
