So, I'm getting the 'Beth quest' bug (the principal's announcement not triggering when entering the school after talking to Tom). I looked for info and saw that it seems to be related to visiting Marcus' home after watching him with the principal. The thing is I didn't. I was following the walkthrough, so I avoided doing that. I followed all the recommended steps to fix the problem by using RPG Maker Save Editor, but the 578 switch square was already ticked.
Did anybody have the same issue, or should I be proud to have experienced and entirely distinctive bug variety?
EDIT: Nevermind, it's the order of the events as stated in the walkthrough that is wrong. According to the walkthrough, the announcement is supposed to take place before talking to Marcus, but it is actually the other way around. I visited Marcus at his home and the next day the event triggered. I'm clarifying this just in case someone following the walkthrough encounters the same issue.
