A few days ago I encountered a weird situation where I fought an enemy player in sierra caves and suddenly he made 3-4 bursts in a row. I thought I might've been a high ap build, but I healed up hid behind a corner and ended my turn, I instantly got another turn. It looked like randomly one of the players got 2 turns in a row, it happened 2-3 times for me and that other player during the whole fight. Is it a bug or something connected with the sequence speed?
