Property of WeldConstraint not been sync correctly

[wingedrobin]

In v7.0.0-alpha.4, syncing .rbxm or .rbxmx file who contains the WeldConstraint, the property part0 and part1 are always been cleared in studio.

Reproduce steps:

1. Create a new Tool with 2 Parts, and use then WeldConstraint to weld them together.
   

2. Save the new Tool to file as .rbxm or .rbxmx

3. Restart the place file or open another one

4. Sync the .rbxm/.rbxmx into the place with rojo

5. The property part0 and part1 of WeldConstraint are cleared.
   

Not sure the other properties are synchronized correctly or not. Maybe the WeldConstraint is not the only property get failed during syncing. Follows are the warning message of my project when connect to rojo in roblox studio.
