Time Shifts after June 30 update
After the June 30th update, in-game time has shifted forward by about 14 hours. My game time showed 7:09 am on Wednesday when I loaded up for the first time after the update, which it wasn't when I logged off after last playing. Neither of my sims would be awake at that time, yet they were up and still doing what I had left them doing previously. I don't remember the actual time it was when I last logged off, but it was late afternoon on Tuesday, around 5pm.
Festival times have also shifted, seemingly by about eight hours either forward or backward, depending on the festival.
Geek Con is from 6pm to 12am while it previously ran from 10am to 4pm.
The Humor and Hijinks festival is from 8am to 2pm instead of in the evening time.
The Flea Market is from 6pm to 2am instead of in the afternoon.
The Romance and Spice Festivals are from 8am to 4pm when they used to be evening events.
The Festival of Snow runs from the oddly specific times of 5:59am to 2:59pm.
The festivals are also shown as less frequent on the calendar. I saw no mention of that in the patch notes. The San Myshuno festivals seem to be only occurring every four weeks instead of every two, and some are on different days. Geek Con was always on Tuesday. It's now on Thursday.
I play with mods, but this occurs with mods disabled as well.
