Base area is a cold village. Every time a Wandering Trader spawns in, it cause a huge lag spike. Unable to move or moving becomes jagged briefly. This might be a separate issue from the lag that has been plaguing all of us. This behavior seems to happen where ever we are, not just at our base. The host is on Xbox while the other uses Android. Both players experience the lag spike.

This happens on a single player survival world as well. Both worlds, no cheats enabled.
