Marcel has completely re-written the skin.helper addon that is used in the majority of views to obtain discart, some views still use the old skin.info.service which still works ok. Please check you have the latest skin.helper and all it's associated dependencies. I think Marcel has pushed it to the repo now but if not you'll need to get his beta repo and install from there.

This is for Krypton

Hmm, I installed the latest script.module.simplecache, script.module.skin.helper.artutils, and script.skin.helper.service from Marcel's github and disc art in boxsets still isn't working and now I keep getting Skin Helper Service error popups in Kodi.

I have the same issue
