@themastergamer43 Well, I just checked it out on mine and you're right. They changed it. You have to actually do the acceptance speech now to get the award. That makes it more of a bug I think.
You just have to make sure to do it before it ends at 11pm. But as I said, you can just bogart the mic when someone else wins if you can't get to it when you win. You'll still get the award.
I tried it several times and when my sim won the first time, the "accept award" action automatically came up, but as I said before, the "watch" action didn't automatically cancel so she didn't do the accept action. I didn't accept it myself so I sent her home and she never got the award. Tried three more times (since winning is apparently random) and the next time she won, the "accept award" action came up again and I made sure to cancel the "Watch" action myself and she accepted it just fine. The award ended up being in her household inventory.
Apparently, another bug is most famous sims end up going to the award shows at 6pm Sundays. The winning sim is chosen from famous sims currently on the lot. So, if you have a save that you've played for a while, and have a lot of famous sims, the chances of your sim winning greatly decrease.
