The Elder Scrolls Online was randomly deleted off my system.
Now that I have to wait another 4 days to play again, anybody else ever have a problem like this? I only deleted those failed to upload notifications and some cloud storage data and when I came back to the home screen I couldn't find ESO anywhere. I checked in the library and it said that I could download it.
Edit: It seems that more people are having this problem every now and then. This post may be old and only 40% upvoted but it might be useful to others. The deletion was not harmful to my system and I was able to redownload and continue playing, it was just a hassle. So don't worry if it happens to you because its just a bizzare coincidence of some kind. Enjoy the game!
