I've hit a glitch where after completing the available content in 0.4b that upon saving and closing the game, half of the gallery scenes have re-locked. I also can't get past 'hug' with the brunette nun on the dates anymore no matter how many times I attempt the date. Additionally, if I load any older saves the quests are all deleted and replaced with the text of the final quest.
As a side note, is it impossible to access the halloween and new years events in 0.4b? Would I need to install an older version?
