Yea, I know k4->k5 is supposed to result in the SS path that's not a bug, but it's bugged if you go k4->k5 and then you refuse Alessandra.That's not what PL described as a bug though. He was saying entering the SS path is a bug...when it's not. Never turned Alessa down doing that route though, shall have to try that and double check with the latest available version as it should be the exact same version/part of the script as the normal SS route which does work perfectly fine (by next scene...you mean with Alessa in the pool before seeing Celeste)?
At the pool, she gives you a footjob and you can accept to become her secret sub. But regardless of what you choose, she will show up later with Alyssa and pretend that you had accepted (even if you didn't). And then you tell her you're not gonna eat the dogfood or whatever it is, she gets pissed off at you.
