Alright, so I decided to try out this game and as I finally loaded into the world, I was met with solid ground. Then randomly, the ground turned transparent and my game lags because of it. I thought I somehow clipped through the ground so I did /suicide but that didn't work as it brought me to opaque ground which randomly turned to transparent. Note: I can see the parts of the map that all the sprites are blocking.
