1. they work for

Work(research i think)
Nursing Mothers
Food eaten
villagers age

2. yes but the update must be from the site you bought it from(the one that shows up after LDW logo, if nothing appears it means that it came from LDW, but i think reflexive didn't put their logo at the game) just a thought


3. this happens to me also, i think that it varies on the game speed

example

2x speed 0 - 2 minutes

normal speed 0-4 minutes

1/2 0-8 or 6

i dunno

correct me if im wrong
