Workshop blueprints not going onto paths-resolved..

I think I've figured out why some blueprints won't go onto paths and others will. The blueprint contains a shop or facility which cannot be place on top of paths. If you place the blueprint in a non-used area, then delete all the shops and facilities, you can then multi-select it and save it as a new blueprint and place it on top of a path with no "obstruction" issues. Apparently the same thing happens with entrances.
Devs, please remove the flag that prevents us putting shops and facilities on top of paths. It is very limiting.
