Did not get achievement for killing Lich
Same problem here, only got the ach after the third kill. (Had gold event everytime) Asked ppl on the map channel, they told me they had to kill it more than once too to get the ach.
I had the same problem. Killed it 2 or 3 times before I got the achievement. I thought it was because I was guesting on a different server. Was using a necro and all skills, and I did get gold event status and chest on the times I did not get the achievement.
