Hey Jienagamblu!
I checked the game, and I canāt see anything wrong for now — but letās make sure everythingās working as intended.
To make Yoru drunk, you need to give her 3 Vodkas in a single day the first time. After that, only 1 Vodka per day will work.
About losing 1 SP, that might be because SP is capped at 10,000 (while other stats cap at 1,000). If your SP is already 10,000, training wonāt increase it — and may display as lose 1 SP on display.
If itās still acting weird after checking those, feel free to send me your save file here: https://forms.gle/sUi6xTUwDVMebUGMA— Iāll be happy to take a look and fix it for you!
