I am getting lag spikes, which are caused by this mod (according to F5). I had those lag spikes when I used AAI zones and
AAI Programmable Structures (Maximum ms is around 150). Without those mods the maximum is 3 ms.
I deleted it, but tried to recreate it and the issue didn't show up. I think when I was trying to make a circuit my circuit created a bunch of random zones or something, which caused the lag. Sorry for the incorrect bug report.
AAI Programmable Structures causes UPS spikes when generating new zones Via AAI Zones, most likely an inconsistency of the mod trying to place zone settings within the subsurface, this is most likely the case. Since the game loads/creates all zones via world creation or surface load
