Short description of error
I've created few child objects under a plane object (similar to video https://www.youtube.com/watch?v=t6__uLJGGFA ). I used an array modifier and tried to export it both with 3D printing plugin and with help of STL extension - both resulted in exporting only first segment correctly and then only replicating plane object. I even applied modifiers but without change. OBJ exporter doesn't have such problem and correctly exports all child instances.

Exact steps for others to reproduce the error

You can apply modifiers, but there is no difference
Export whole collection either with 3d printing plugin or with default STL exporter
Only first collection exports correctly, then only plane object in contrast to OBJ exporter
