I just got Meditation 3 and the quest that goes with it - which is to achieve max relax and gain 50 energy.
So I've been meditating where I can to try and get this. The first time I heard the noise and saw about half of the rainbow appear... But then it didn't complete itself, said the usual distracted thing, and didn't count for the quest (I assumed someone had given me a random kindness but the logged showed that this wasn't the case).
The second time was just now, I meditated for a while, saw the full rainbow appear with 'max relax' on it... But the message I saw said the usual got distracted, I gained 54 energy and since it didn't seem to count the max relax, the quest still hasn't completed.
