I found a bug 1) and endless loophole 2), dont know it its intended, or triggered by her stats. started a new game in 0.8.0 continued a bit after 0.9.1
now in 0.10.0 i just completed the 1st bj mission and the work bj from maya "misson" and safed before am i in love y/n night self questioning.
1) after the bj, i interacted with her for another bj, but as i had conodms in inv, it triggered a visual sex secene, but by story i had not "asked her" yet for first time
2) so i thought there might be any bug so i set condoms from 2 to 0 via an save editor as it never said they are nessary so i passed time forward till next evening (not night as it tells by mission)
i let her cum first by massaging, then she demands to instert it too, but you cant, cause without condoms theres a loop, as she doesnt want to get pregnant..
i hope this is helpful for makeing this gem-game even more glorious.
