The main problem is that if you can't complete some lower-level goals, you don't get the higher-level ones and there is no way to know if you'd have gotten a gold medal. I just threw a dinner party where besides "call to meal," the other first level goals were all related to multiple Sims doing something at the same time. Even though I "completed" those goals, they never turned over to reveal the next level, which means the highest medal I could have gotten with the goals I could see would have been silver.
I'm not sure what the solution is besides hoping it gets fixed ASAP, but there really is no way for a player to conjecture what their final party score would have been in the scenario I described.
If certain aspirations are removed from scoring, then a player who completed those aspirations may be penalized because the time they spent on them could have been devoted to a different aspiration that they did not have time to complete. This is going to be a tough call for the challenge team.
