Celris
Plantera
You need to wait until the mod is compatible with 1.3.1.I have an issue on the 1.3.1 version where the textures of all the items are in the game but they alll replace normal items.
for example, the spectrum helmet (I'm pretty sure that's the spectrum helm anyways.) replaces the texture of one of the campfires, and the dulling talisman repalces a sensor of some sort.
