Return of Reckoning

Is it normal for cannons/rams to disappear from your backpack after you spawn them? (one use)
or is it normal for them to stay in your backpack permanently? (infinite use)

I assume it is totally normal for oil in your backpack to disappear after one use?

I cannot currently access the bugtracker and currently i wouldn't know what to put on it, this concerns my 'Kagaz' char.

oil is consumed. 1 use.
ram and cannons are permanent.

Thank you.
