That's a lot to say in the title alone, so let me elaborate. About 2 days ago I published my latest project. When I was logged into my account, it would show up on my userpage. However, when I was not logged into my account it would not show up at all. It was as if it was never shared. However, I could still access and play the project through its URL, it just didn't show up on my profile at all. It was absent from my projects bar and from the “featured project” box, where instead stood the formerly featured project of mine.

After about a day it finally works now - the project can be seen to people other than me when viewing my profile. @jvvg also told me has experienced the same problem with a project he shared the other day. So it seems this may be a common trend.

If you want to test it out, create a project, share it, log out of your account, go to your profile, and see if it is there or not. If it's not, if you log into your account again it'll probably show up.
