Gut shot bug?

Should second boss of siege be casting gut shot mid air?

Ran a 16 last night for the Tuesday deplete (+2d it, still died to necro because I spaced it) and I noticed that Gut shot was casting while she was mid air from the boat back to the battlefield. The debuff applied to a random dps player so I know it went off and I was standing directly next to her when she landed.

I ask because gut shot is her stationary mechanic to prevent ranging her and it does a fair bit of damage, but there is no counterplay for that.

It’s finicky, generally when the cannoneer dies I make it a point to run back to her landing spot while one of the dps or healer shoots the cannon. I’ve noticed that if I’m not there she’ll sometimes shoot people, I also pre drop consecrate and taunt as soon as shes in range just to be sure.
