Woops, looks like the build wasn't set to the master branch - build should be updated and shown as 13038,
Oh man, yes, git allusions, talk dirty to me, baby. <3
Does it take a few minutes for the servers to update and show the downloads? I still am seeing the same thing.
I'm sorry if I'm being terribly impatient or maybe I bought the wrong thing and only paid for the Windows version of the DLC.
