The parkour mechanic is broken, sometimes when traversing the trees if you jump too many times in succession you will eventually soar off into the distance and completely miss a branch and land on the ground. This will ruin your movement on the ground. You cannot climb back up into the trees, you cannot execute, and sprinting is a bit weird.
The easy fix is to just leap, because when you leap the game doesn’t recognize you on the branches anymore giving you normal movement back.
