In fact, I'd call Pacers are allowed to keep the extension, since i'm sure it was uploaded already with sim 12.
so i'm 100% sure everything was done 100% right
but i also would have voted my extension came in time back then if you remember (*)
(*) the only bitter taste for me is this: Once sim 12 is finished the simmer can see/know the player resign offers, so he COULD check before carrying out the extension (and again, I'm 100% sure you didn't do). In my case I posted well before player offers were announced so I COULD NOT have know before posting.
(and that's what's so sad about Orlando-Gate, still, 2 seasons later ...)
