Even the link on your twitter still works.
Edit: The Bug Report section maybe restricted to game owners only which is why the link still works for me, but not you.

1. The spelling error was on the store page, no patch was required to fix it.
2. The thread was not deleted, it was moved from general discussions to a sub-forum specifically for bugs.
3. The OP of this post complained on twitter and on the forums about something that was fixed within days of it being noticed.
4. The developers of Paperbark are really cool and decent people, you should check out their game and ignore this guy.
