yes honey. I have done basically everything that is possible in one save, that's the problem. Leon event is the only one that I can't
I don't know what to tell you. To check, I just started an entirely new game on the Patreon version and played through everything to get the requirements I listed and then I got the Leon Park event and it worked fine. So long as you don't pick the options that end the conversation, you can eventually ask "Something wrong?" and then that leads into the sex scene.
