We've had the same 3 towns controlled by 3 different shadowlords for more than a day now. Yesterday we had tier 1 spawn in each of the towns. When I got back from work none of the towns had any spawns and they still have no spawns. I am getting the distinct impression that our shard (origin) isn't capable of going from first tier to 2nd tier of the invasion. Has anyone seen second tier of the invasion? In other words, have you seen an invasion that covers the entire city?
