1.7-1.12 Models Exporting In A Broken State

[TheDec0ded1]

What are you trying to do, and what do you expect to happen?

Attempting to export 1.12.2 modded entity models, and expecting the files to be mod-ready after adding the right imports.

What happens instead?

The model fails with "cannot find symbol" errors for some of the cubes in the model. I've attatched a .zip with one of the functional .bbmodel projects, and the exported .java result.
