So earlier today while playing the new hot and hazy update I realized I needed to go and get ant mandibles so that I could fix my ant club but when I looked around for soldier ants there were none to be found, but lucky for me I remembered that there was a ant hill not too far west of the baseball. So I head over to this ant hill and at first I get hit by a small amount of lag but I didn't think anything of it knowing that its probably just spawning things in but the second I took perch on top of the hill to find some soldier ants I started lagging so bad I couldn't even input actions and I ended up dying to the ant which is not a major problem but if this were to happen while I am in the middle of the labs or worse it would be awful. I play on The Xbox one and have not had any lag issues like this since day one I hope this helps!

The reason why there is such bad lag by the red ant hill is because there are like 200+ ants in the anthill and that is just too many ants for the xbox to keep up with. I think it's because the worker ants are laying eggs too fast. 

Im having the same issue, there are a lot of ants. I try to avoid that area where the ant hill is nearby the first research lab. Lag in there is just unbelievebul

This was an issue during the public test too. There are too many worker ants now and they lay eggs too fast so the whole nest respawns in like a day. Also I think the grass in the grasslands area is taller and denser since the update.
