Just quickly reporting a bug caused by this mod- if you try and customize Peach Lizards (the new yellow-like lizards in the Watcher DLC), they cause a very bizarre pseudo-game-freeze that locks up most game input and graphics, but weirdly the game keeps running underneath. It seems to be caused by the game failing to load the Peach Lizard's head stripes, judging by the relevant portion of the exceptionLog:

NullReferenceException: Object reference not set to an instance of an object
Watcher.PeachHeadStripes.DrawSprites (RoomCamera+SpriteLeaser sLeaser, RoomCamera rCam, System.Single timeStacker, UnityEngine.Vector2 camPos) (at <477ce972de094f10bdadd556875c57af>:0)
LizardCustomizer.LizardHooks.LizardGraphics_DrawSprites (On.LizardGraphics+orig_DrawSprites orig, LizardGraphics self, RoomCamera+SpriteLeaser sLeaser, RoomCamera rCam, System.Single timeStacker, UnityEngine.Vector2 camPos) (at <65c4add675204f0bb8739042d4ba4109>:0)

Blizzard, Basilisk, and Indigo Lizards all work completely fine.
