Again, for the last time, I followed the wt, looked into the laptop on beach day, no sign of camming with Evelyn. Then I did go on in hope it would show up on the day after, sadly it did not. Going back means for me to restart again, for 6th or 7th time. I won't. Sorry.
IMO it was a mistake to put a side quest trigger on one specific ingame time. Side quests should always be independet to each other and to the main. Just my 2 cents. Maybe you can make something out of it.
I wish you good luck with Ch.1 and the following ones. But I'm sorry, I won't play it anymore.
