I'm from India and tonight (friday 20 june 2014) at around 10:58pm a sight happened to my downloading notification bar. I was downloading ESPN FC FOOTBALL AND WORD CUP app and suddenly after reaching 100%.
And time 0 seconds left the download kept on going and as it passed the 100% mark the time started to go in negative and this continued for about 6-7 minutes.
Please let me know if there is a problem in my android device or it's an error from the play store. After some time it ultimately installed the app but it kept on closing automatically. I uninstalled it and when I tried to install it again from play store it downloaded but after reaching 100% it said 'a fatal error occurred 961'. I was using a MOTO G XT1033, non-rooted.
Here are the images:
