When importing a project... sometimes all the parenting gets reset to "None"
I just discovered a bug where if you import a project that contains parented layers... those parents will suddenly be set to None. However, it only does if you previously imported 2 other projects. Here's an example:
Here's a title project I imported... notice the parenting seems fine.

And here's the same project imported a second time... it's parenting is also fine.

But now I import the exact same project a 3rd time and now the parent is set to none which completely messes up the project (none of the layers are where they should be):

I used the same project in my example, but it happens any any project I import on that 3rd time.
Anybody else notice this?
UPDATE: Make sure the null layer is the top layer. If the null layer you're parenting to is not the top layer, then the issue will happen on the 4th time you import, not the 3rd.
