Some Sims 4 players have reported that after installing the latest patch, their Sims have become unreasonably hostile toward other players. Unfortunately, the issue currently affects many players, all of whom report that it has never occurred in their games. \n \nThe Sims 4 receives frequent updates, which might include new content (such as expansions and stuff packs) or improve existing features. Unfortunately, as with many previous updates, this one appears to have unforeseen implications, such as Sims aging at an excessively high rate. \n \nSeveral people have posted on the EA support forums about how their Sims have suddenly taken to being harsh. Traits that generally make a Sim agreeable and sociable are being used against them, with sociable Sims suddenly being aggressive and beginning conflicts with even the most amiable Sims. Also, it's not just the player's Sims; even NPCs have started acting more hostile lately. This problem appears to affect Sims at every age. \n \nPlayers have stated that this is a significant problem because it drastically alters the interactions between Sims and the Sims' behavior. Since this issue is actively affecting gameplay and causing damage to relationships that players have worked hard to create between their Sims, gamers with long-running save files are especially weary of playing until this issue is rectified. The problem is autonomous. Thus there is only a practical way to control it if gamers wish to micromanage their Sims' every move. \n \nThe Sims 4 is long-running and sophisticated, so it stands to reason that issues will arise with subsequent upgrades. In the past, patches have fixed everything from minor bugs to more outlandish occurrences like alien abductions resulting in male pregnancies and the My Wedding Stories game pack launching with certain features broken. While it's irritating, all users can do is make a backup save and keep EA informed of any problems they encounter.
