was looking up all the titles and noticed a nice one that I wanted: Telara's Defender

now that title is listed as acquired by Clobbering Cultists (2500 cultists killed)

after hours of grinding I finally complete the achievement only to find out I have not gotten the title

bugged?

feel like I just wasted a giant amount of time for nothing, i dont mind putting time into a game for something when I can but when I do and get nothing its not very fun
