Your minion.xml is a little messed up. You can either delete it and restart Minion (in a terminal window: rm ~/.minion/minion.xml)
Or you can edit the minion.xml and remove any of the following 2 lines...
Open it in your favorite text editor with the path ~/.minion/minion.xml.
Code:
<game addon-path="L1VzZXJzL3N0YW1ib3VsaWRpcy9Eb2N1bWVudHMvRWxkZXIgU2Nyb2xscyBPbmxpbmUvbGl2ZS9BZGRPbnM=" display-name="Elder Scrolls Online" game-id="ESO" unique-game-id="ESO-1"/>
<game addon-path="L1VzZXJzL3N0YW1ib3VsaWRpcy9Eb2N1bWVudHMvRWxkZXIgU2Nyb2xscyBPbmxpbmUvbGl2ZS9BZGRPbnM=" display-name="Elder Scrolls Online" game-id="ESO" unique-game-id="ESO-1"/>
You have 3 of the same addon paths in your minion.xml and Minion is confused.
