+1 on this perspective. I make a lot of wits. That means frequent late and flameout additions with same/similar ingredient additions. Even when I still bottled I did not have the problem you're describing.
That said, what time in the boil did you add the peel? Was it zest or dried peel?
On a separate note, what style was this beer? If a wit or other wheat (except for a Kristalweizen) whirlfloc would typically be deleted as an addition because you want the beer cloudy.
