After MC gets back from Roma, I started getting unbalanced <<click>> macro errors for the stairs going down to deck 7 from deck 8 and the stairs going up to deck 7 from deck 6. When I edited the passages in Twine, it appears the author was trying to cover two <<click>> macros inside if-then branches for the Chloe Quest with a single <</click>> outside of it. I'm guessing Twine/Sugarcube has a problem dealing with the generated html due to some sort of scoping issue? Also I'm surprised that it took so long into the content before this started when it probably should have started erroring out as soon as MC got the quest somewhere around day 3 and not day 23. The attached html fix puts two <</click>> tags inside the branches of the if-then in place of the single one outside of them.
Note that this fix will trigger a new passage where Chloe pesters the MC about the headband before getting a link to proceed to deck 7. It also appears to cause the headband to finally become available for retrieval for MC when it was missing before when the MC gets to the passage where it appears.
Also there appears to be some sort of event in Tara's cabin that triggered for me where MC was sent up to the sex shop to get some lube. That is a problem because the link for condoms and lube returns a "not implemented yet" error. Looking at the passage for the Sex Shop reveals that a state variable $sexs is currently set to 7 for me when it needs to be higher than that to open up the lube options. So the Tara event is probably triggered for the MC too early in the content
