Issue:

I was traveling across my world with the Resonating Wand in my offhand. It was daytime, I had been searching for crystals the previous night and had not swapped it out yet. So I had probably had the wand in hand for at least 20 min. The crash happened twice in the same area. Taking the wand out of hand stopped the crashing.
