Thank you for your time answering.Updates from chapter 2 onwards have become very linear, and most new updates have requirements on scenes that lock you into seeing all of the previous update before you can see any of the new update. 26p1 is a great example of this. A lot of people were unable to view any of the new scenes because they had not done the last Maki scene from the previous update. So I don't think we're going to see another Schadenfreude situation (where goodhomie actually required you to wait until after v.8 to see content from v.6 to avoid blocking out content).
The Seeing Red situation is a lock contained within a single update. Abyss and the Onsen series were both added in v.15p1, the order we viewed them determined whether we'd miss content in 0.25p2, and the game specifically tells us to visit Yumi first, which most of us probably interpreted as "do a Yumi event before you go" instead of "do all the Yumi content before you go." Well, at least I did, so I missed the full locker room scene last update.
So the situation you worry about really can't happen anymore. But we need to pay attention when the game suggests an event order.
