Hiiiiii, um not sure if it's intentional but if u do the cross-date with Ashino and Kadsey twice , Kadsey doesn't appear again :(
I actually completely forgot that happens when I replayed it myself so it was a nice surprise. Kadsey SHOULD appear again, the switch should get turned back on if you do the date again and I just downloaded it and tried it. Hmmm, are you playing the newest version from a few months ago? Let me know if it's still doing that.
