It's not a bad thing at least esp as it would be an absolute nightmare to play walkthrough less if it was too specific on trigger timings for events and we ain't short of games which require 'Thursday x time , y room after z stats number reached'. Nobody likes those in all honesty and can only imagine complications with fluidity (which kinda are already there) with more girls being added yet minimal restrictions to focus on faves first so events can be referenced in scenes you might not have seen yet as you maybe followed a newer girls route first. There are even continuity issues with using specific girls content like say Ashley where you can take pics of her in nurse costume and she'll say nice excuse to use it again or the likes BEFORE viewing the scene where she surprised you with it for first time.
If it was a simple "Talk" scene, then there were times in the walkthrough where you would get the hint to talk to them at certain times of the day if they'd normally be unavailable at certain times (i.e, Kali at work or Ashley in school).
I understand that some people can be a bit impatient and want to unlock everything as fast as they can, but it should be understood that doing so is likely to cause continuity problems or (in the case of certain cheats) could risk breaking something.
If it
is doable to add those extra triggers to delay certain events, then it'd be up to Runey to decide whether or not it's worth doing.
