New Substance Plugin doesn't handle moving sbar files properly in Unity

Been using the new Substance Plugin for Unity (beta) that got released end of March 2022.

Upon importing the package, it updated all of the existing sbar files and introduced a subfolder for each instance of the Substance.

If you move the sbar file and its subfolders to another directory, any attempt to do anything will generate an error because the sbar file is trying to find tga, materials, etc that were in the previous hardcoded path rather than relative to its new location.
