Found the bug, thank you for the report, I have fixed it!
As far as I understand, you got this message while searching the web at the principal's office, correct?
If so, please do this to quickly fix your save file (If you don't want to, it's okay,
but you will skip 1 future search the web event):
Go to the city, open the dev tools by pressing F12, (while the game is open of course) navigate to the console by pressing on the "console" button at the top. Then enter this command:
SugarCube.State.active.variables.workweb = 9
Then, click enter and without refreshing your game, go back into your room. Everything should be back to normal from that point onwards
