First of all the missions in my country’s hours refill at 12, 3, 6, 9 PM etc. So they’re really easy to keep track of.
I finished my last missions somewhere between 13:30 and 14:30.
Checked the game at 16:40~ only to find that my missions didn’t change. So they should have changed baring the fact that the 3 hours were up by an hour and 40.
Have a screenshot.
