After casting Boomstick the character stays in the gun wielding idle animation, but with no gun or melee weapon in hand. This persists for roughly 4-5 seconds even after using other skills like Raptor Strike or kill command which makes your melee weapon magically reappear then disappear again between attacks.
It’s incredibly annoying and further immersion breaking bug for a skill that has been made a core part of the spec and just one more thing to tack on to the list of criticisms about it.
