Can someone clarify how loading works with crossbows? The description says you can fire only one piece of ammunition from a weapon with the loading characteristic on "an action, bonus action, or reaction", no matter how many attacks you have. Does that mean a) if you use your action to fire a crossbow, you can't fire it again until the next round, or b) you could theoretically fire it up to three times in one round: once with your action, once with your bonus action (if you had some kind of ability that allowed it), and once with your reaction (again, if you had an ability that allowed it)? The only real restriction, in the latter case, would be that you could not use the extra attack ability to fire a crossbow more than once with your action.
