Monsters don't attack as 15 hours

Hallo All =)
Monsters don't attack as 15 hours/

During this time I had already spent half of the research, and even not interesting without attacks.
Base monsters eat, but they sit and do nothing =(

Help ! Won 2 times first time 8 hours, the second time for 15 hours and neither one attack...

Did you accidentally played in peaceful mode? When you create a game there is a checkbox where you can select an option that enemies won't attack until you attack them.

Make more pollution and they will get mad.

With a really good location, you can play really safe.

If you manage well your pollution and you are also surrounded by Forest, than you are really safe.
