Huh yeah, that option is totally missing. There are a few times when it seems like I've skipped content or it was a fast transition (for example in Paz's route when I'm training with Gunnar then suddenly end up going to the hot tub lol).
But, I'm pretty sure it's just the polyam route that's specifically buggy for me, with the early errors and then the missing dating option. They just both seem to know I'm dating them both without a conversation and then Dyson brings up a convo we never had about me dating Gunnar only, then I either pick to marry Gunnar or not, with no other options. So it's like I'm in the polyam route but it gets confused and puts me back on the Gunnar ending.
When there's a new version, I'll try the route then as I think it just went wonky when I downloaded it and I'm too technophobic to know how to fix it lmao
