Subject: [PATCH] Fix peeps not showing on one side of pirate ship (#16499)

This commit fixes this bug by adding a missing ^ operator on frameNum.
Before a recent refactor, the framenum was changed to the mirrored one
with "^ 1", but it was omitted. Using "^ col" when col is 0 or 1, adds
this back.
