I'm planning to upload a build to the workshop of a barn i built. But the grouping systen is confusing! The build is in multiple groups and i wanna combine it to one but its not giving me the option to do so. Apparently there is a difference betwen "scenery selection" and "building selection" and scenery can form groups but builidngs cannot? Ive tried seperating everything into seperate pieces but then it just either lists each individual group into a scenery selection or a building selection
