I've not had the algae problem either. But I've purposely kept my population down, except that one combo of herbs in the stew that made everyone feel..........friendly, lol. But thankfully no babies were made, whew!
I keep seeing people talk about time warping, I just couldnt do that. I am running at 2x speed and sometimes I still think it's going too fast. It's about the journey more than the destination, right? lol.
