The fix is for v0.7, using it on 0.7.1 actually removes some fixes I made after that. I just left it here for the people who don't want to download the full game again, since all the bugs are fixed in both.
If you followed Kat and the variable isn't triggered, that's because I introduced it in the update after the one that introduced the scene itself. I don't remember the version number, but I remember having mentioned that you need to start a new game at the release. Same goes for this update, you need to either load a save from the morning of day 9, or start a new game and since you probably didn't restart the last time it was required, I'd do that now, otherwise it will only get worse with every update.
I see, thanks for the heads up.
I started playing this update from the scene with Jada in the bathroom but I do have a save right at the 'Day 9' screen (I always save at those times). I missed things like this because I tried to avoid spoilers by not reading too much the thread before I actually finish playing the update.
Another issues I had were with 'of11' name not being set (probably same thing, was set at the start of the day 9 I guess; just gave a random name and it didnt bother me again), something about 'mainbgm' not being set (same thing I assume, its during the Hanna scene) and three missing renders: d10night20, d10night21 and d10night22 (on the night of day 10 with Ellie and Jada). Its the three first renders when you pick Ellie.
I will re-play from the start of day 9 and see if theres anything else happening, and if it does I can fast-skip from the start until this update scenes.
EDIT: So the 'mainbgm' error of it not being defined happened earlier this time, at the start of day 9 after Ellie leaves the bathroom, when the breakfast scene is about to start. Guess I will have to play from the start indeed.
