Update: The new game update that was just released fixed most of my issue. Although it seems like rain still does give me slight performance issues, just not as horrific as it used to be. I can jump in water w/o my game "going out the window" which is good.
Harvesting does not affect me on Xbox One, but the part Auldrick said about the animals in MC not being able to follow you or find a path to you properly, does affect me.
I got this bug too in 1.13.1 :/
