The trash before the boss “Operator Thogar” seems to be bugged currently (at least on Normal 25). When the first set of trains comes and unloads the “Iron Raider” NPC’s, there is one Iron Raider on each train, in the exact same position in both carts, that does not jump onto the platform properly.
These NPC’s are targetable but you can not attack them. I have tried using Spirit Wolves, Earth Elemental, Capacitor Totem, everything in my toolkit to try and get these guys off the train but can’t.
I have also tried leaving the instance and logging out, waiting for the raid to soft reset, and trying again and the exact same bug with the exact same two NPC’s keeps happening.
The current workaround is positioning yourself just before the largest post of the chain-fence before the cart. There’s a deadzone that you can fling ranged attacks at the Orcs.
