Well, that was unexpected.

>I couldn't think of a snappy title.

I was doing Castrum Meridianum and got a pretty bad DF group, however I just ignored them and continued my way, healing and buffing. We got to the airship bit and it seemed the Colossus' bugged out and they just started smashing the Anti-aircraft cannons.

We couldn't lure them from that area as they shuffled along the ground, it took them 45 seconds to get from one cannon. I'm not sure if they're meant to keep attacking the cannons or what, but it was rather funny.
After we did the first part of the boss, the barrier drops and they just kinda came in and killed us, lol.

Same thing happened to us lol.

Was hilarious to kill the boss, and then came back to see that the Collossus killed the tanks and healers, and someone ran away from them and activated the final boss so we all died.
