10km Portkeys showing the boot instead
The last 2 or 3 10km portkeys I have unlocked showed the boot instead of the soccer ball. I had both a 10km and a 5km unlock around the same time. The 5km portkey showed the kettle like it should but the 10km one was showing the boot.
While not that big a deal, IMHO, I was getting use to seeing the different images for the different portkeys when unlocking. Cant pinpoint exactly when I noticed it showing boot instead but probably after I finished bonus tasks with last brilliant event and started picking up regular portkeys again.
