Repeating pause every second on my bases only

Changed Status to Known Issue

I see the hitches you're describing, taking a look now

Changed Status to Fixed

Framerate should be smoother on the next update that hits the testing branch. If you're curious, the part that got optimized was the "auto-wrangling" setting on critter dropoff points. I didn't end up checking the control group saves you posted, but I'd suspect they either didn't have that setting enabled anywhere, or had far fewer critters on the map. Thanks for the report!

Thank you for the quick fix and the explanation, the repeating pause completely disappeared.
