i'm sorry for asking help to something that already has a guide but still.
pls help, I can't make the ship as ammo catapult to work
it worked at my 3rdish try but it doesn't work again

-new ship design(make new fleet, add a ship fitted with the new design)
-upgrade halo to fire
-map view then catapult said ship to target

repeated these steps dozens of times now and i can't make it work again and I'm tired T-T
