mayor gifts

I'm also in the dark on this one. Really when do they reset, I just see them gone.

contacted ea to really find out what is going on

reply from ea they reset every 24hrs for visting other city's 

and gifts from your own same way they will get less and less as you collect them and then you must wait for the 24hrs to reset aka new day

sounds fair.

I usually visit other cities till i find cash and then wait a while before doing it again.  Gives me a slow build up.
