It has something to do with using python scripts to inject the interaction into a list, rather than manually adding it to the game's XML file and using that edited file as an override. Problem is, I'm so far having trouble getting an injection to work, myself. The override method is working for me fine, but that method creates incompatibility problems.
I can explain about these lists a little bit (at least, on the XML end), but I feel rather out of my element on the subject since I haven't gotten an actual injection working yet.
