Hey all! A common point of failure for Sims 4 users seems to be attempting to run with Sim 2 or Sims 3 mods. Running with Sims 2 mods will result in a cryptic “required game data is missing” ...
Anyway creators are well used to having to update work to allow for patches etc, it won't be a huge shock, compared to the hours that must be spent by EA helpdesk on players wondering why their game won't run.
