Checkpoint proximity and enemy respawn bug

Running around Freythorn and wound up finding two checkpoints practically on top of each other, wound up dying. Every time I would respawn I'd get dogpiled and immediately killed by two swarms of mobs on either side of me. I couldn't reset the instance because I couldn't move far enough while alive to the waypoint, and I couldn't portal back to town because I was getting eaten up. Eventually I had to get my friend to pop in real quick with his endgame character and clear up the screen for me so I could leave.
