A month ago I uploaded a game called Titan Punk Concept

Even though I uploaded the game with this account, it doesn't show up under the my arcade games section:
Not really a big issue; I did have some trouble finding the game because the arcade doesn't have a search feature, and forgot to bookmark the game page.
