In my live link options there is no box for World Transform, causing the camera to snap to 0,0,0 as soon as I load in the data from the UE150.

We are very sorry for the confusion, we will need to update our documentation for UE4.25. The World Transform parameter moved to the “Role Controllers -> Transform Role -> Live Link” section for the LiveLinkController, see the attached menu screen grab. Please confirm that un-checking the World Transform checkbox fixed your issue.
