This sort of thing happens all the time during pilot season. What usually happens next is that Wayans' scenes in "New Girl" would be reshot with a different actor, who would continue on with the series.
But not this time. So, we're going to get a different actor (Lamorne Morris) playing a different character (Winston) in Episode 2.
That may have saved money on reshoots, but it seems unnecessarily dumb.
