This mod or one of its requirements seems to have broken romantic interactions, i assume after a recent patch. I have 2 sims that are dating, but recently they can only do a single vanilla romantic interaction every time the lot loads. After that, only modded romantic interactions show, with the default ones just being gone. This issue applies to all sims, dating or not. I removed all mods except DD and requirements, and was able to narrow them down as the cause. It works fine without mods/with other mods.
