iT2D 1.5 Bug - Multiple Level Mounting objects is broken when added via the UI (ITGB-287)

Build: 1.5
Platform: XP
Target: Editor and Stand Alone (not tested on device)
Issues: Levels that were produced earlier to version 1.5 that contain multiple levels of mounting fail to load correctly. The objects all end up bunched around together. This bug can also be recreated in new levels produced using the editor for 1.5.

Steps to repeat:
I have also managed to recreate the problem in the same way that Craig Jorgensen of PocketPlayground did:

"I went and applied mounts to alot of the objects in the feature demo menu and now it is exhibiting the same problems of objects being way off their mount points.

Here is the levelSelect.t2d file from the feature demo that shows the objects out of position.

Suggested solution:
It seems like this is a recent bug that has be created as part of the upgrade to 1.5.

BTW - if anyone wants to share the source to 1.4.1 then I'm happy to chase this down myself - I'm just unable to access the old source since upgrading to 1.5 :(
