Messed up ProBuilder UVs in build

Hey everyone! Everything is perfect in the editor but building the scene out messes up most of the UVs on our ProBuilder object. We are using Unity 5.6.6f2 and we recently updated to ProBuilder 2.x. I tried lots of things but nothing helped yet. Any ideas why it happens and how to solve this problem?

 

@Leaflux have you tried to export your model out to Blender (or whatever 3D tool you are using?) Just wondering if it might still be OK when it gets there, then you could recycle your models through a 3D app. At least you could then see if you can (or can't) get out correct UVs even to your 3D tool.

 

I thought of that but I haven't try. Even if it worked we have too much PB objects to export and reimport all of them. Disabling Static Batching solved the problem though so we are okay for now.
