So the cosplay outfit in the sex shop is setting an incorrect variable, $hasahascosplaynalbeads, to true. Should just be $hascosplay.
Bro event 4 is pointing a goto event 3, and the linkreplace to goto Interactsam isn't working correctly. Not sure why, so I just pointed it to his room instead.
Jess event 4 is also pointing to event 3, while looking for the $anal variable. Just the variable. Should be looking for it to be false.
The mom repeatable get eaten out is looking for an incorrect variable $momlust to be greater than 650. Should be $motherlust. And before anybody freaks out, these link to PNG's. Not video's or GIF's.
I couldn't figure out the broken week counter, but if you open the console(F12 with Chrome) you can manually change it with "SugarCube.State.active.variables.week = 2" to get the dad event.
Here's an edited HTML with the fixes mentioned, except the week counter. There's a few if else errors in a couple events, but they're all viewable and update stats as intended.
