Requesting Help Regarding RenderTree

[ocarina0001]

Hello!

This is a bit of a longshot asking the forums, but I'm trying to create an update to my RainWorld mod that adds a new animal which switches textures at night. Everything does work, but I am getting the following error:

Attempted to draw OCARINA_LanternMouse5538 without a resolved render tree.

This error occurs whenever a new LanternMouse using the "night" textures is loaded for the first time, and I'm really not sure what to do about it, because it seems like this type of error is incredibly rare with only a handful of reports regarding it. Below I will be linking to a Google Drive of the files pertaining to the LanternMice. If anyone could help, I would be incredibly grateful.
