[LE] QueueNiNodeUpdate not updating appearance

[l1ft0ff]

The title says it all, but to elaborate, I'm trying to use QueueNiNodeUpdate to update a change to the player character's appearance but it's not doing that, which to my (possibly limited) awareness runs pretty counter to what the function is supposed to do. Instead, an item that occupies the body slot must be equipped, or a save must be made and the game returned to title screen/save reloaded. Yet, I see mods like Realistic Needs and Diseases 2 use it (e.g. after increasing the player's weight in response to checking and verifying that the player is staying well-fed). More importantly, the racemenu and the in-game console command for changing player weight aren't victim to this issue so surely there is a way, right?
