I'm enjoying the game, but I have the following problem
If I leave the game for a long time (over 24 hours?), the monsters don't pop up or they become very slow.
I don't know if this is an intentional limitation or not, but the same problem continues even if I restart the game, and if I turn it off for 2-3 days and turn it back on, the monsters pop up normally again.
Is there anyone else experiencing the same problem as me?
