This patch should (hopefully) fix the "too many threads" crash several people have reported.
In addition, there were 4 achievements listed that were never really implemented. These have been changed to new achievements (because that's what was partially implemented).
The old achievements were:
Combo Prince
Combo Princess
Combo King
Combo Queen
The new achievements are:
Combo Hero
Combo Champion
They are essentially the same, just without the gender requirement.
