Root cause is too much computation each frame... this is greatly reduced when the center face finding algorithm is eliminated. I imagine there is a much nicer way to do this elegantly... ideally a Blink that is removed from the flower can be replaced and simply work, updating its face to find the center, as it currently does. This is already reduced by only resetting the face if it was previously alone... but this does cause the issue of not resetting the center face if 2 are removed together or similar.
