How to reproduce:
1. Open attached project "2018.4-bundle-loader-minimaltest.zip" and scene "SampleScene"

3. Observe the textures on the models in the Scene View (there is a custom script on each object where you can offset the UV's by clicking Up/Down)

Expected result: the textures on the models looks normal after the bundle is loaded
Actual result: the lightmaps and albedo UV's are swapped
