Steps to reproduce:

With Collaborate enabled,
- User 1 creates a cube in the center (0,0,0) of a scene, saves the scene then syncs it with User 2.
- User 2, after syncing the changes from User 1, moves the cube to (5,0,0) and creates a sphere in the center (0,0,0).
- They then publish their changes using Collaborate.
- User 1, before updating to get the latest changes made by User 2, moves the same cube in the same scene to (0,0,-5).

Expected: This should create a merge conflict.
Actual: After pressing reload, Cube is placed at (5,0,-5). Values seem to be added together
