No. That sounds a bit harsh, I know, but it takes a lot of time to change the area, even just a little bit. You can follow our Facebook page, I will post a status when I'm enlarging areas.
The map isn't as perfect as we want it to be, sadly. There's no way to find out exactly when a Monster is despawning, so we have to use a lot of math to try and guess it. And even though this method is very accurate, it isn't exactly perfect. Sorry about that.
