I ' ve had it bug out on me four times now on my priest . 3 of the four times , half my army gets combat bugged , and the night elf chick spams my chat saying something about getting wrapped up in cocoons , then they just despawn , killing most of my army . The 4 th time was clicking the telemancy orb through the night elf chick that spawns the rewards at the end . It acted like I clicked the orb rather than her , and I got ported out after a 2 hour clear with 40 minions , spent on about 6 chests , with nothing to show for it . It ' s never not been buggy , and it was okay for a while , and it ' s super easy when you have all the upgrades , but man . every time I do it , it seems I wipe or lose out on upgrades for a bug , which never feels good .
