WR in the Any% category does not have an attic, therefore skipping straight to the library and saving a minute.

Has this run been submitted to the wrong category or is there a different Steam version that is missing part(s) of the game and is publicly available?

The WR now (8:31) showcases that is is possible to achieve a time of 8:52 or lower with the addition of the Attic. I do not know what version of the game that run was performed on so it will not be moved from its current category.

Duly noted.
