Confirmed. The bugs are repeatable, not isolated case.
Still investigating the reason, but it is quite hard because going back and forward with huge amount of object is a pain and slow.
For these which is about to upgrade to this version - DO NOT, You will destroy your projects.
Big projects saved with previous version will be permanently damaged !
My current suspicious about the cause of the bug :
- Instance of many objects which is internal for TM.
- Deleting parts of objects.
- Changing rotation of parts of objects.
