I was playing around with large drones. Made a super planet killer using the 'alltech' cheat.

Drones don't move in demo, so it didn't work.

But that's not the point of this post.

The point I want to make is that this drone had level 21 cloaking, and if I turned it on and moved it one sector to a planet sector (in system view), then moved it next to the planet (in sector view), then turned it off (in system view), it wound up having zero supplies. Even if I used the 'restoresupplies' cheat first, the short period of cloaking used up all supplies (and it had 12 max level quantum engines). Does cloaking really use supplies that heavily, or is this a bug? Seems like a bug. Doesn't really matter in demo since drones are disabled anyway, but would be bad bug for full game. I mean, doesn't everyone want to make super-cloaked planet-killing drones?
