GameObject missing in TestFlight build but not in AdHoc build

We have a number of assets that we assign in the scene as normal. They work fine in Editor, they also work fine when directly building and running on device. They also work fine when using an Archive build with AdHoc target.

When we build to testflight it seems that there is at least one model that doesn’t correctly load and we are completely dumbfounded on why that is the case.

We built a Development build and pushed that through testflight and we now see that indeed while the GameObject itself is not null as per the go != null check, accessing it returns a null reference exception. This is extremely weird, has anyone else had this problem before or does anyone have any sort of guidance what might be causing this?

Ok, forget this post. Our build pipeline had a slight difference after all, missing Blender in it so .blend files were not imported.
