Having multiple addons installed in one world causes the world storage space to randomly decrease and causes lagging after 10 minutes of gameplay.

I have about 10 addons installed on my world. Every time I start the game. It randomly starts to decrease my world storage randomly. After it’s done loading, the storage rapidly decreases. Not only that, but after 10 minutes of gameplay, my game starts lagging and starts messing with the FPS and randomly decreasing and increasing over and over again. I just keep restarting the game. Mojang, please fix this issue!!

P.S. Please ignore the background noise in the videos. It’s not something to worry about. Also, don’t ask what addons I have installed. It is none of your concern.
