A couple of bugs (latest public version, 1.19):
Android: No way to access save/load/quit menu
Android and PC: Calling Ash after getting her number for the first time triggers the topless sunbathing with Vicky scene. On android, I was not able to go to the beach or call Ash again, effectively locking the game. On PC: I was able to go to the beach and do the topless sunbathing scene, even though didn't have a swimsuit or nearly high enough corruption. After that scene, calling Ash again triggered the same dialogue, asking to go to the beach with Vicki, however, I wasn't able to actually access that scene on the beach again. Eventually I was able to go get Vicki's new swimsuit and triggered that mall scene, but after that, I was unable to call Ash again, go to the beach, or do anything with Vicki. In addition, I was already able to sit next to Vicki in lecture, see her pictures and raise her corruption, even though I hadn't technically met her (hadn't triggered the scene with Ash, don't have her #, etc.)
