Reg & 2v8 Macmillan map - cannot pass between rock and trees

Macmillan map both on regular and 2v8, cannot pass between trees and rocks that are close to each other but should be passable still, but acts as if there is an obstacle in the way.

Step 1 : Boot the game

Step 2 : Play as Survivor on Macmillan map 2v8 or reg

Step 3 : In-game, try and move between a tree near a rock but with a gap that should be passable

Step 4 : Notice that you will not be able to pass between the rock and tree even though in other spaces you can.
