Activation of the system without anything to reload (all loaded) weapons still costs the 25% of total flux, is this intended? I would assume from the "NO WEAPONS TO RELOAD" message would stop it from consuming any flux.
Also of note, Sometimes, the reload bugs out, IF you fire a missile launcher that fires in a burst, activating the system instantly discharges the whole burst in one go and reloads it, BUT on occasion (and I notice it tends to be the currently selected weapon) will not reload when you use the reload. It'll leave most times only one weapon that doesn't reload ( could this be the jamming thing the codex says about the accelerated ammo feeder?
)
Edit: this is with alternating, linked seems less... buggy.
