Tried to do this mission just before and this happened, couldn't warp because I was kept in combat for some weird reason so had to reset the game EUPS server Yeap that's Robin stuck outside the battle area after the cut scene at the begin
Had this happen several times recently (USPC). Eventually just stood next to Ivy and let her kill me... so slowly... because I couldn't be bothered running the whole instance again. It seems like he's prone to lunging past you.
