I don't think it was mentioned that they are changing anything about the previous update unless they stated something like that only in their discord
Ah, ignore me. I may have misinterpreted or read between the lines on the update they gave, where they said:
"That being said, we have slightly expanded the scope of the update to add a little extra touch to an important scene. Although we went back and forth about it, we think that without including it, we would not be delivering the experience we want to. So, despite the fact that we are pretty close to our estimated delivery date, we have committed to adding that. As a result, we thought you should know that there is a possibility that it might not arrive in the window we are targeting. If it doesn’t, we believe it will not take any longer than the end of the month (to be generous). "
I was assuming that they might be adding a little something extra to see something of what Luna went through in ep 6. I mean, they still could be, so we'll have to see. If they do, I don't think it will be changing episode 6 at all, it might just be a small flashback or something.
