I experience a quick lag spike every time I cross a specific chunk on my single player world. I did some testing and I realized that the lag only occurs when crossing from this 1 specific chunk into the one next to it. This lag only happens from this specific chunk to the other. It doesn't happen with any other chunk crossing into that specific chunk and it doesn't happen going from the chunk back towards the chunk that I just came from. (going from chunk a to chunk b lags the game, but going from chunk b to a doesn't) I made a new world with the same seed to see if it was something related to the world, but I didn't experience any lag. This makes me think that it is something specific that is causing the lag. The thing in my world that is closest to being rendered in/out when I walk around those 2 chunks is a mob switch. (a mob switch is an area in the spawn chunks with 70 mobs that don't de-spawn and take up the mobcap and that prevents most hostile mob spawns in the world) The mob switch itself doesn't lag my game when I get near it so I'm wondering why I experience lag when I potentially load / unload chunks near that. I'm not exactly sure what this is so I hope that I can get an answer to a solution if one exist. Thank you for reading
