A few other problems with black and white parties:
1. The playing chess objective applies 'only' to the first, cheapest chessboard (i.e. the one that's black and white itself). The other chessboards don't count. Either the description needs updating or the objective should be able to be satisfied with other chessboards.
2. The 'listen to classical music with 3 sims at once' is not correctly working. Note that this was attempted with musicians who had the appreciate interaction and not the listen interaction. The objective log registers 1 sim listening when you choose 'appreciate classical music' but if in a conversation with 2 other sims and the action 'appreciate classical music together' is selected, the log resets to 0 sims listening. Attempted the same with 2 household sims in a conversation together, and the log will register 2 sims listening if both are listening to classical independently, but if one initiates conversation with the other and chooses to listen/appreciate classical music together, the log resets to 0 sims listening. Either the interaction is flawed, or the objective list isn't registering the group interaction correctly.
