Follower State Not Displaying (SOLVED!)

The "ring" state for my follower never displays. Its idle, hurt, and lose sprites all display at their appropriate times, but the frame for "ring" never shows, whether I'm grabbing rings or using them. I suspected it may have something to do with the Duration line, but I've tried changing that to no success.

Spoiler: The code, in its entirety
