A 197-page thread on the Ubisoft forums (reported on by Eurogamer) features a number of players saying the same thing: they can't play Watch Dogs after redeeming uPlay content on PC, PlayStation 3, PlayStation 4, Xbox 360 and Xbox One.
These people are referring to a number of extras that are available to those who interact with the uPlay app or via uPlay.com. As an example, players can unlock a gold-colored D50 gun and the Papavero Stealth Edition car that helps you evade detection, as well as cash bonus reward and a uPlay avatar. It's the first two of these perks that are apparently causing problems.
Some users say that booting a save, the progress bar will load to around 90 percent and then refuse to move further, leaving players stuck at the title screen. Ubisoft says that it is aware of the issue and is working on a solution.
"We're aware some of you are stuck on the loading screen," read a message posted to the official Watch Dogs Twitter account last night. "We're hard at work on isolating the problem to find a fix."
"If you're encountering that issue, please submit a ticket to http://support.ubi.com to help move forward. Thanks for understanding."
It's probably best to not mess with those uPlay extras until after Ubisoft implements a fix...
We'll have more on this story as it develops.
