When Maria was at level 29, save a file and try doing Maria's tasks. If it still doesn't work, you can try changing the language to try it out.I am using Chinese
If it still doesn't work, please take a look and see if there are any saves before level 30 to try, because I unlocked all the characters before elevating her to level 30
30 to 31 are automatic departures, no need to buy Elves，31 to 32 is what needs to be purchased，Skip a few more days and take a look.If it is 31 to 32, it will automatically trigger after you purchase the Elves, and then release Maria
28 to 29 go to the bar in the evening，29 to 30, have a conversation in her room，30 to 31 are automatic departures, in the morning Maria and Hanna will come to see you for the hospital check-up after Maria is taken away after buying the Elves, she will be released
