Hello! A few days ago I noticed A profile I follow has uploaded 3 new projects, which can't be found in search. They can only be found when opening the profile page. His name is NightPlayTV and his projects are ghosting away.

There are three problems with your post:

1. Don't you think it's the creator's problem to ask this question?
2. There's a Search and Browse FAQ you were prompted twice to read before posting here.
3. I don't see why you had to create two different topics to ask the same question.

For what it's worth, at least one of the games you mention was published less than 24h ago. Indexing takes a little while at the best of times. Hope this helps!
