Yeah, that is a lot shorter code, thanks for the tip, I'll update at this was a pretty early creation when i was learning code... also, it's better to fill in that gap with a redundant failsafe as if one was to get destroyed while no cryofluid was being fed to it, the reactor would detect that there is no processor and resume, exploding in the process... which, did happen in the development of this module, as one flare was able to take out cryo fluid production and the one processor... so now, it's much harder to do as there is now 3 targets to destroy before the reactor explodes opposed to 2... and there is much more safety from a ground attack as they would need to go through the reactor in order to blow it up, which, would prevent it from blowing up...

However, you do make a good point, I could've easily left all the processors on the left side of the reactor, opposing the cryofluid intake and it would've achieved the same thing...

also the code can be made much shorter

Double failsafe seems really unnecessary, the logic processor controls only 1 reactor, don't think it can fail doing that
