Well i started playing last night and i thought its the lag that made the mobs, my beginner horse and some NPCs go invisible, but when i played during the "fast" hours, its still invisible. The mobs are invi but they can damage me, same with the begginer horse, it's invisible but gives me movement speed. and NPCs, well, they are invi so i cant click them.

I wonder if its the game files and i need to redownload
