Make sure you have all the required mod dependencies, and their requirements. commerce core, quest core, other core mods etc. Then try walking in and out of the H10 apartment. Hopefully that fixes it :)
Great job! I love this idea having vendors for the custom items. It may be extra work some modders don't want to put into (such as additionally creating atelier shop) but it's wonderful addition for those that wish to indulge our immersion!
