It was all great fun but after two hours I noticed, I wasn't getting attacked Aliens I tried two bases since then and I've streamlined my production line a bit but I still haven't been attacked once.
I'm wondering if I'm just not causing enough pollution to cause them to spawn bases around me or what the issue is as I've pretty much got everything I need set up right now to progress for a long while.
Here's a picture of my newest bases production line

Am I doing something wrong? Everything is set on medium I didn't use peaceful either. Do I just not have enough automation to be attacked? That maps five hours old and I haven't seen an alien yet and I've afked with it on for an hour.
I built turrets at the beginning just to be safe but ultimately never used them. hence my ammo count.
