Hi @Marzolan,
thanks for reporting this issue and for looking into this.
Unfortunately, it looks like a failsafe / shutdown optimization mechanism is triggered here that I implemented some time after I came up with the breeder. I'll look into making it possible to disable it.
If you want to play with it please have a look at lines 131 - 141 in /usr/lib/draconic_control.lua.
function DraconicController:decideShutdown(reactorInfo)
if reactorInfo.generationRate == 0 then
return false
end
if reactorInfo.fieldDrainRate * self.drainback / reactorInfo.generationRate < 0.7
