Love this mod but recently started playing Industrial Revolution and while the tech is re-searchable the actual entity is unbuildable because "repair-pack" is replaced by the IR mod to differing packs for the different materials (copper,bronze,iron,steel).
It was a simple hack to make it work changing "repair-pack" to "steel-repair-tool", I'm a novice when it comes to modding but I believe your mod could detect if IR was loaded and change the build requirements?
