Report by MrMentor:
"In RU Campaign two missions are not awarding progress towards hard/all-medals achievement.
RU8 - There is if/else statement that is awarding either medal1 or medal2, but never both.
RU11 - Condition for medal 1 is wrong. It should be less than 4 people dead, but it checks for more than 4 people dead."
If a user has alot of saves, it can take a long time for the load/save dialogs to appear. Switching to staggering the preview images would allow them to instantly appear with the preview image being loaded every few frames in the background.
