Is the veteran spawning anymore? I've just started doing this achievement, and no matter how far my crystal is - 50% or higher, the veteran is not spawning. Just regular mobs :/
While we're on the topic - I can't seem to get the Crimson Sunflower for this event. The one at Craze's Folly is unpickable, and when the event in Seitung spawns, the flower doesn't stay in your inventory :( Any tips or tricks?
