The warning that a craft is out of electricity starts spamming when it is at 0 electricity but still gains a little bit of it. I suspect this is because it gains some, but uses it up immediately, then gains it again and so on, causing the warning to trigger evertime it is at 0. This persists even when not controlling a craft and is very annoying.
The spam went away after using the boosters of the effectet craft. I think this is because it generated electrcity.
