I am level 6 trainer, and I have had 3 incense. I've used 2 already, and the description mentions 30 minute duration. However, both my incense lasted only 20 minutes, and the time bar(circle?) looked like 1/3 of it was missing.
Is this because of my low level, or a bug? If a bug, is there a way to get my 20 minutes of incense back?
