It was only applied to wild cloaks and not nomad cloaks in general, because devs hate Wilde. )
Uhm, in fact, nomad ships - or bodies - exist of energy, able to run the cloak. (Cloaks are nomad tech anyways.) So lore-wise it makes sense, that nomads don't need anything to run the cloak. Actually, they shouldn't even have to buy them but have them automatically with the ship itself.
Still, we could give human ships some kind of "powercore" commodity, which gets destroyed every time the ship is destroyed. And have it cost 4 millions, too.
In the end, I don't care for having a death penalty or not.
