Deactivated thrusters after powerdistributer modification any idea how to bring it online again?
At a guess you got hit by a negative effect on a low level mod that tipped you over the edge on power requirements.
I expect you'll need to update your auto power management options in the right hand panel, or do some minor utility/module changes to compensate.
Prime candidates are turning off things like cargo hatch and fuel scoop when weapons are deployed by setting them to priority 3
.
The change I've been making on several ships is to ditch an A0 shield booster for a point defence module instead.
This helps two ways. With the notable missile buffs the point defence is now a useful module and it frees up a little power for other things. Obviously my shield power isn't as good, but everything is a compromise on ship builds when power is limited.
