Possible bug: PoE2

Hey everyone,

I just noticed something. When actively in combat with multiple enemies present, if you trigger Toxic Growth < Gas Arrow, Vine Arrow, and then Poison Burst while Ravenous Swarm is active, it procs Caustic Ground, which then causes DoT to your own character.

FYI, this doesn’t happen when there are no ad's around.

I even tried adding the Commiserate Support Gem, thinking it might offset the effect, but unfortunately it didn’t.

So now, every time I enter combat, I’m basically getting wrecked by my own abilities.

Did I miss something with these skills? Is this intentional, or is it a bug? Just trying to figure out whether I should submit a it or just accept it.
