If I understand this correctly, a full new episode 5 is coming now - and then I have to repeat everything completely in the next update, even the new episode 5 I've just played? Sorry, that doesn't make sense to me, I would have released the revision of the old episodes first and then the new chapter 5. With this order I would have to repeat "only" the first 4 chapters. But so I have to replay all 5 chapters afterwards - or skip that episode 5. But then again I have to ask: why release the new one now when many will wait for the revision anyway?
Well, good luck with that, but I will definitely skip that one.
