QA from Senmomo here.
In regards to the prologue patch, Pomelo and I are working as much as we can to get the prologue fully edited and QAed for release. It'll be on the slower side, however, because we both are quite busy and can only work when time is afforded to us. It'll take some time to do, but we'll definitely get this patch out.
As for how much progress there's been, we've edited and QAed a good amount of the first script. The TL is complete for the prologue as well.
