Upland has been making a lot of changes recently that have seemed to impact standard and competitive treasure hunting and not only has it become more difficult to actually find the treasure chests without a mega sized web in a city but the payouts also seem to have been reduced too in terms of how often they pay out nice sized treasures like this one.
It's been several days since I've really gotten much more than the city minimums but today I finally hit a nice one. It's uplifting to know that these are still out there and that you might just have to do more hunts to find one of these.
Either way treasure hunting is still a great way to supplement your earnings in Upland.
