Sometimes when I hop in a demolisher in Isle of Conquest, I can’t use the ability set to number 1, which is the projectile ability. I can still use the ram in slot 2. Hopping out sometimes lets a new pilot use the ability, but in my last game, neither of us could use the cannon. /reload does not fix it either.
