Tbh I think you should just pause lins updates until the others catch up. I mean, it would be a shame as her events are the best - but id personally much rather wait and have it be easier for you going forward to write with full freedom.
What I mean is that it kind of puts you into a corner where you can't really change your plan at all. Like let's say for instance (hypothetically) while writing more of the twins story - you realize you want to have some big thing where felicity loses an eye or something (and you recognize that this change would vastly improve the story for some reason). You'd have to go back and edit all of lins events from this point forward (including this nexus one) to incorporate that change. Which may make you, even if subconsciously, less willing to make this change to your plan even though you think it would make for the best story. Id rather you delay lin's events than put yourself in that position.
To help in the meantime, Maybe add to the current disclaimer that "events preceeding this are not yet complete, proceeding will be immersion breaking". Atleast until they are all caught up, at which point you can make it so the event can't trigger till those are all completed.
Of course do as you wish. Just trying to help. I have been there before with painting myself into a corner and it really ruined my motivation going forward. Dont want to see the same happen here as this story is fucking fantastic
