Hey,
only place that involves randomness is the dice game outcome. So it should always be the same as it just checks for certain values and we've not heard of similar issues before.
So perhaps some choice was picked different and that big was enough to shift it to a different outcome.
No guide though, no. The Discord's got a spoiler chat where occasionally you have people asking for some scenes and getting answers for that, but we don't plan on making a guide anytime soon (if ever).
