Fixed the karin_qa.txt issue and updated the patch.
The saveload issue may require some more heavy lifting. I will PM Bokun and enlist his help for this. For now, you should save at the schedule screen.
Focus on intelligence first, as this unlocks new commands which are more efficient, lvl. mind and body to at least 2 to be able to use them effectively... if you do all 4 blowjob training scenes, you will unlock a new "service" command which nets you more money.
Leveling mind by using calligraphy or ballet will increase your available willpower, increase its recovery rate from rest, and also you can buy recovery items once you get to the shop (in month 2).
To fix it, you have to open karin_qa.txt and remove all additional "
Ex.
addTextSelect 0,""Master's hard cock feels incredibly good!""
addTextSelect 1,""He was late, yet incredibly unbothered""
to
addTextSelect 0,"Master's hard cock feels incredibly good!"
addTextSelect 1,"He was late, yet incredibly unbothered"
Do this for all lines starting with addTextSelect and you are good to go.
