I have already been exploring in night mode previously, but recently, I cannot explore in any location in night mode to complete tasks. A pop-up box says "sorry, this mode is not activated", even though I already had been exploring in night mode. Any ideas? Is this a bug that was introduced in my installation? I'm running on a PC with Windows 10. Thanks for the help! -Jon
