I noticed this odd thing in my goli. Even though I only have an XC on board (300 cu), it says 466 used out of 600, while I had no cargo on board at all. While controlling the capship.
So
Is this intentional, or just a weird bug?
That seemingly my addons take up the ships cargo, what make no sense to me
As a lot of the cargo is just unusable
I suggest to fix/remove it.
I had a queen mining beam, two gemini turrets and a default neut turret, and obviously the power cell. What is exactly 166 cu.
Idk if its a bug or not, so wrote on suggestions instead.
I noticed it like fifteen minutes before writing this post.

However it works just fine if I am only docked and not controlling the capship.

This is why its weird.
Compare it the the cargo used on the HUD

This is not a Suggestion. Moving to General since you are unsure if it's a bug.

Thanks Whistler

It's got to be a bug. Why would addons equipped count as cargo?

Yes, it is a bug. It's counting addons as cargo. It'll be fixed in the next client update.
