Unusable cannon glitch?

[Legion Of Metal]

This may be something that people already know.
But when i have an enemy ship incoming directly to me. i want to use a cannon.

Sometimes what will happen is that the cannon needs loading. Fine...? il just grab an iron ball?
Then it comes up "you cannot use this on this artillery piece". No matter what type of ammo i try to use. its the same message. so then i cannot defend myself and thus doomed to die thanks to the game literally and physically stopping me from fighting back.

Is this a reoccouring problem? or am i just cursed? this has happened more than once. Is there a bug that exists or something and is there a current way to counter it?

I haven't had this happen to me before. I would double check the ammo and make sure the cannon isn't already loaded or just needs a push forward.

it happens yes i think it's a glitch,someone else has to fire/load that cannon in order for you to use it again

I've noticed this bug as well sometimes, I just switch to weapon by scroll wheeling or pressing 1-4 then I take a new cannonball and it works again.
See if that helps if you get bugged.

Its a known bug I've reported it several times
