Good to know. It's to bad that its broken and cant be fixed. BTW, BTC block numbers are already generated, there are 21million block numbers. Just pick one, they are in sequential order. So yes, I do expect to see a block number published somewhere (which is not well documented). It should be placed on the site in a prominent area (along with server seed), not hidden in some twitter file that no one is ever going to open or even knows exists.
We use the 12th block mined after the lottery round closes. Although it is obviously possible to predict the 12th number in a sequential numbering system of +1 it is not possible to predict what block number will be the last one at a specific time.
We use Twitter to publish the file as it is a third party, Tweets are timestamped and you cannot edit a Tweet.
Anyone who reads the Provably Fair tab (that you obviously didn't) would know where to find it.
Have you finished making a fool of yourself yet? It's not broken, your comprehension is.
