Iron is far too much of a bottleneck, ash execute and iron all have parts of their animation that are not shortened by the speed upgrades and this drastically slows them down later on (Ash for example, from 0.3 seconds, to what feels like about 0.7/0.8, significant when you can't automate ash)
Most of it seems ok, no saves is a royal thorn
And if the ash update hasn't fixed it already, you can shock your population again if it captures before the animation finishes- this will only give you the heat and ash of the last time you pushed shock - could sacrifice 400 people (300+100) and you will only get the latter 100 worth of sacrifice results
