gl on your run

Ah, that could be my problem. I did add to an existing save.
I'll try again for my next run.

As well as creating new designs

Clear design works too

This could happen if you load a save game which didnt have the mod before, the easy fix is to just click Auto-complete in ship designer and it will fix itself

I must amend my previous comment. It is actually broken mechanically. If I select a Booster, it replaces the hyperdrive, filling its graphical slot and somehow it makes the Hyperdrive count as empty (not the "No FTL" option but a null) leaving the design invalid as a core component is not filled.

Thanks.

Minor issue, I activated both, and I'm running UI Overhaul Dynamic, and now, everything seems functional, but I'm having a minor graphical glitch.
In the ship designer, every Core Component (Reactor, Hyperdrive, Thrusters, etc) when clicked on instead shows the options for the component above it. Thankfully I can still get to all of them, due to a blank slot (I presume the one intended for the Reactor Booster) at the bottom, so everything works, but it is an odd graphical mis-alignment.

Both

If I'm running both CSS and NSC3, which version of the Better Reactors mod should I be using?

Yeah now that i'm thinking about it i'd say nullification protection would be better for reactor boosters, and either also give them shield hardening, or perhaps add a third required component that works similar to shield hardeners,but also gives something like shield hp or something.

The only issue i could see is that if you made more of these mods then you'd run out of vanilla aux modules so you couldn't really specialise since you could only have 1 of each type instead of maybe going for full reactor boosters, or full afterburners, etc

The logic behind giving nullification protection to reactor boosters, would be something like having reserve power to sustain the disruption from hazards. Though it could be given to shield hardeners as well, to give them more purpose, especiialy in late game

Absolute genius idea!

I didn't even know that "shield-nullification-nullification" was possible, i always basically ignored shields because they are so unreliable compared to armor because of things like neutron stars/pulsars, space storms, missiles, torpedos, disruptors, strike craft, arc emitters, shield disruptors, etc.

I would love to see shield nullification nullification in some ship component in the future, although idk if it would make sense to put it on reactor boosters, or if they might need their own kind of required component that might be a replacement/equivalent to shield hardeners, and maybe have something similar for armor for the rare case of your ships being in that weird toxoid system where armor is nullified instead of shields?
