Sims 3 Update out (1.18/2.13/3.9/4.6/5.4/6.1)
Patch notes found here:
Some of the important ones for Late Night include:
- Sims with the Artistic or Virtuoso traits now improve the Bass, Drums, and Piano skills more quickly.
- Butlers’ will no longer park their cars in front of client Sims’ homes for extended periods of time.
- The height of framed photographs on a wall can now be adjusted.
- Fixed an issue that caused babysitters to appear in private areas of high rise buildings, thus preventing them from successfully caring for the child.
- Fixed an issue that prevented the Disgusted moodlet from being removed when spoiled Plasma Juice is removed from a Sim’s inventory.
I didn’t see anything about increasing the band gig rate and many other things, but I’ll need to play the game to see if they did end up getting patched.
EDIT: Started up the sims and got a gig for my band within 5 minutes.
