Erika Boss bug

[Boghald]

Hi! There is a bug, at least, with Erika boss (I don't know other bosses). I was battling her, I setted the field with Stealth Rock and 3 piles of Spikes and I ended the match using Roar with my Skarmory to wear Torterra and Tangrowth down. The problem is that when Torterra came into play (last pokemon alive), he died but apparantly there was another turn. I chose an attack (Roost) and suddendly it was displayed "Torterra has fainted", and the match ended without any reward, no money and no pokes. I talked Erika again and she told me we have recently battled. The worst thing is that the consecutive wins has reseted to 0. So I guess there is a bug with winning a match with entry hazards.
