This still feels like it belongs to the bugs & troubleshooting sub-category.

When searching for a player, adding a space at the end will not recognize the word. I've tested it with the shop and games, and it works since it's probably using a different form validation? I'm not too sure.

Maybe a trim()'ll do the work or something else, since usernames aren't supposed to contain a space anymore.

usernames can have spaces in their names now you need a membership for it

Ahhh I see. I forgot about that. Thank you for letting me know.
