[NGS] Gunner/Fighter with a Twin Machine Gun/Saber multi weapon, using skill Julian Dance causes issues with Gunner's chain

I've been seeing some weird behavior with my class setup as stated in the title. When I start without a Gunner chain active than use the skill Julian Dance a chain is randomly started after I use a few uncharged Gunner PA's or Normal attacks and suddenly ends without me using a charged Gunner PA to end the chain. Its super weird that a chain would even start at all because Julian Dance isn't a charged Gunner PA? Maybe a bug with how Gunnar + multi weapons work?

I have this happening as well, except for gunner + talis multi weapon (I have a bug report on this as well). There's also reports of the chain ending randomly as well. Seems like gunner is just bugged.
