We noticed some areas have increased lag, it is ambient but also makes other lags worsened like the inventory lag bug.  

The notable areas with increased lag are areas with high building density and large inventory.

However, these lags were minimal before the recent update.  One of my friends gets super laggy and can't go near my base in survival because since the recent update the lag is so bad.

It is confusing why there is so much lag when the Xbox One is MORE than capable of handling this game, especially when its hardware specs are better then most typical gaming PCs!
