Nipper's with offset framestyles not working

[Void]

So this has been a bug since 1.4.4* and it's been somewhat bothering me for a while, not as much as others that have been fixed, but still. Anyways, giving the Nipper NPC the SMB3 style (with offset) framestyle makes the advanced offset work in editor mode, but when testing the level, the advanced offset resets to the first variation. In my situation, I want to make two different sets of graphics for the Nipper NPC, one for when the advanced setting (Fiery Walking Piranha) is unchecked, and one for when it is checked. It shows up correctly in the editor, but not when playing the level. It just defaults to the first offset.

*(In 1.4.4, the offset wouldn't even show correctly in editor mode either. Not that it matters now, but I guess a little bit of trivia???)
