The game has been working for me lately, even without loading my inventory. But I do feel your pain. I was not able to play fireworks for most of October. Mansion was my first game, so either I went back there and made whatever credits I could, or I didn't play at all. Even if I couldn't play mansion well, I would have played it anyway. Practice makes perfect! 
I was going around VMK to try and load as much clothes as possible. Go around to the popular places until I didn't see anybody with the blue swirl. By doing that I reduced the crashing quite a bit. In the last week or 2 I have not crashed at all and I noticed a different behavior at the end of rounds. At the end of round 1 I notice that it takes additional time for all 3 players to get displayed. Sometimes 1 or more players will pop up after a delay. I'm guessing that this was what was causing the crashing before. By going around VMK before playing Fireworks and loading all the clothes you decreased the chances of crashing becuase somebody in the top 3 were wearing clothes you hadn't loaded yet. ALso possibly explains crashing in later rounds. If a different player ended up in the top 3 you crashed because they were wearing something you didn't have loaded.
I'm sorry you're still having trouble with fireworks, Mint.
You know, I hit a Mansion milestone yesterday... my 500th loss!
I'm really not terrible at Mansion, just mediocre. If I'm playing the right person, I can get 80+ ghosts in a three round game. It just so happens that the other person gets 90+ ghosts in that same game...
