Hello,
We are playing multiplayer in a group of 2 (Necromancer with minions and Javelin Paladin)
When we get to Lagon for some reason he is fighting and casting his skills away from us as if there is another platform on the other side.
When we kill him he doesn’t allow us to continue with the quest instead he just gives his interaction when you first start the fight.
We killed him three times and it’s the same issue as before.
Edit: Also seems that one player gets locked outside of the platform if another player gets on the platform faster, forcing the locked out player to teleport to the party member.
