With the latest version 3.2.7 FIXED, it isn't playing the sounds I designated for the Application part of the alerts (Unique Monsters, crafting mats etc). I tried to deleting the config file, and it worked for a couple times when I dropped something out of my inventory then stopped and went back to the default sound. Also won't show over lay for Unique Monsters.
edit: Also plays sounds multiple times for treasure goblins.
edit2: Some times when exiting FindersKeepers, it is still running in the task manager.
