Recently initiated a raid on a town, and destroyed a Ravenger and an Evoker, didn't get the achievement for either, was playing on Survival mode. Also didn't gain the Buy Low Sell High Achievement after gaining the village's favor and doing trade with them. The Treasure Hunter achievement was also attempted successfully but did not unlock. If the game isn't going to reward its players with something as basic and commonplace as achievements, I'm seriously about to stop playing.
Thanks in advance for your help
