Bug: When loading saved design, items are 90 degrees off

I have built a few vehicles for different tasks. The vehicles I have saved will load fine, however, when I attempt to attach a block or a wheel, the item I wish to attach are rotated 90 degrees. 

The new block will 'attach' to points, but the bar itself 90 degrees rotated (on a horizontal axis). When I attach wheels, they are rotated 90 degrees (on a verticle axis, so they're laying flat).

I can resolve this issue by removing old mount points (blocks / braces / etc) and re-build them. After that, they are OK. This is HIGHLY frustrating, as old models CANNOT be used unless that section is rebuilt. 

This error is prominent in 0.4.4. Any help?
