Severe issues with Mercenary dodge/reload/shoot

There is a severe issue(s) with Mercenary not firing straight away despite reloading and just points the crossbow without shooting or even shoots blanks which are indicated via a series of rapid clicking sounds (not the same as the ones from reloading, there is a distinct difference in sound effect/number of clicks), this is especially apparent after dodge rolling. These moments of not shooting seem to last several seconds each and are longer than it takes to reload the crossbow which makes it seem indicative at least, of a bug/issue. This is a consistent issue which seems to be occurring about 40% of the time and is leading to some frustrating moments/deaths.
