I went to Xur, saw he was selling "Cerebus+1" and was hyped to get it. When I clicked buy nothing happened, so I went to orbit and back, and he was suddenly selling a different weapon "Riskrunner"... I ended up buying riskrunner, but am disappointed as I'd much rather have cerebus+1, and other people could still buy it even though I could not.
Hello, Thank you for your report. Due to the recent transition to Pacific Standard Time, Xûr’s inventory partially reset at the old daily reset time of 10 AM. We are investigating this issue for future weeks. In the meantime players should expect that Xûr will continue to offer Riskrunner, Transversive Steps, Fr0st-EE5, and Eternal Warrior this week.
