I think as the other mods don't know that the renderer for the lampads has 3 textures, they don't know what to do so they crash literally, with JEI or Blocklings (in the "Hunt" task as all the mobs appear) when they "ask" the other mods for textures, they don't know what to send, maybe put a try catch or idk how minecraft code might work, but if they don't send a "Lampad layer" just put it randomly, or separate the entities into 3 different ones, this is in minecraft 1.16.5. Here's the error:

[01feb2024 18:29:55.619] [main/WARN] [com.willr27.blocklings.Blocklings/]: Failed to render entity on screen: greekfantasy:lampad

I will put the same error on blocklings github and jei too, but this is the error for now, ty

1.16 is not supported.
