22k Problems but a Norn isn't one

Like I said in the last post, I was trying to create a new seasonal migration world for my wolfling run. It has a desert theme, and the only additional metarooms were the Desert Ruins and Ettin Terrarium. I also added in a few other agents and seasonal garden box patches. I thought it looked nice, but wanted to make sure it was actually habitable. So I hatched a few random Norns and turned on fast ticks. When I came back, the world was super slow. I freaked out a bit before I remembered the magic profiler and frame rater.I opened the frame rater up first and learned that I had over 22,000 agents in the world! I then let the profiler run in hopes of learning why my world was being over run with agents..

What came back surprised me: there were 22,683 grazer wastes in my world. I quickly removed them all with some Caos magic and the world sped up. I don't know what caused it, but I'm happy to say the world has been fine ever since.
