Hot fix, reported by the community.

Thanks everyone for reporting these issues

They all will be addressed in a timely manner.

[CHANGE] Expansion cost is now lower, by popular demand.
[CHANGE] Customers are more careful with their budget

[FIXED] In multiplayer, sometimes the changes and the total for the cash register isn't correctly shown.
[FIXED] In multiplayer, the end day prompt is visible throughout the day.
[FIXED] After loading a save, the staff isn't present anymore. This fix should prevent this from happening. (If you loaded a save and the staff wasn't there anymore, I'm afraid they grab your money and ran away)
[FIXED] The "inventory" key tab is now working, and selecting "Nothing" will un-equip your hand-held items.
[FIXED] Staff salaries aren't being deducted.
