Exact steps for others to reproduce the error
The issue: there is an object linked as a group instance from another file. Either it stays as an instance or if I convert it into geometry and unlink it, in render mode or render itself, it's geometry offsets from it's location. The model itself is imported from .3ds file. In the original file where this object was linked from all stays where it has to as well.
