It's mixing the NPC tiles set and the critters tiles set.
Idk what to call this.
Here! Have a picture:
rofl lol rose, it's "gaia lag" where while playing/starting another game/round it changes what set of tiles you clicked in the first place (normally it changes to npc's or myst) just get rid of the orginal tiles (the ones that you click) and play like normal, after a while it'll just be like a normal game just maybe not the one you selected in the first place
TLbiggrinR= it's lag/visual error dont worry about and finish the the game like normal rofl
