Hi, thanks for trying to help! Yes, I’ve noticed there’s an ocean under the map. I went my way to delete it and play a handful of rounds to see if the lag was still there. Unfortunately, the lag still appears 
I’ve tried to maybe find a possible reason by playing about 15-20 rounds to see if there are any patterns going on, but it looks like the lag is randomly heavier than other rounds and seems to be very randomised. Some lag that still occurs is gliding at the beginning of the round and teleporting through walls, and if you spawn on the first floor of the map, you’ll end up teleporting under the map. The memory usage is 75,000; I don’t know if that’s too much. The map is pretty basic, with buildings and trees. Other than that, I have no clue as to why it’s lagging at the beginning of rounds, and my last resort that I have now is to find any possible help.
