Update Ruins Z-Day

[West DEN And East Invaders]

I already wrote this in Ideas for next year's Z-Day.

Basically, this:

1. Z-Day ends at the same time when an update happens.
2. During the update, populations of nations increase.
3. The new citizens always appear as survivors, even in nations with fully zombified or dead populations.
4. Because Z-Day ends, they can't be infected or killed.
5. It is impossible to be 100% dead or infected in the end.
6. This makes the final scores unreliable.
