I followed a tutorial and to my knowledge this mod is compatible with Discover University (patch 1.) and should work with all previous expansions and updates too. In this fix I managed to make the ADHD trait a selectable personality trait for non-pet Sims, added via CAS. The issue was that the ADHD trait didn't appear in the personality traits menu when creating or editing a Sim, but the trait was randomly added to townies and even pets - so the trait existed and worked, but you had no way to add it to a Sim of your choice. Hi! I'm just an avid Simmer who wanted this ADHD mod and was disappointed to find it was broken and last updated in 2016, with no indication for a fix in the near future.
