I'd try this first to see if it doesn't fix things. I can't currently test at the moment but will be able to tomorrow.
Alrighty played through it again and figure I'd just send a small collection of issues I encountered.
In chapter 2, when being cautious about Sonia walking in to check on you after the bath, the sarcastic option is not available and instead I see this error: Error: cannot execute macro <<link>>: unable to parse macro argument expression ""<q>I drowned $them."</q> " + "(Sarcastic +)"": Invalid regular expression: missing /
After playing through it again, choosing mostly the same choices, all 3 options in that scene with Sam are still locked.
Hope this helps, I know how bug squashing can be sometimes.
