Possibly an issue to look into (it may have just been a one-off crash on my end that was annoyingly timed):
Game locked up when Poppy approached me after 3rd period class (was supposed to meet her in Orchard but had the beginning sequence for Queen of The Ring trigger, keeping Jess in the class). After approaching me outside the class and saying all she had to say, she walked to the left but maybe 2 squares before she reached the classroom directly to the left, the game locked up.
(I probably explained this poorly... my best guess what happened is that another "event" blocked her movement path and she doesn't have "Skip if Cannot Move" enabled (which may not even be a thing in VX Ace, I'm not sure since I'm used to MV) so the game locked up as she can't move nor can she skip movement and I can't move until her movement is over.)
Another small issue is the two bad girls in the park who want Vodka before school. I took their quest, looked around for Vodka for a few minutes, and decided to just give up and go to school - ended up being unable to because Missy said she wouldn't steal from them and to either complete the quest or give money back, but... when I tried to give the money back it would just play a scene asking if I had the Vodka yet rather than allowing me to give the money back. (Was it even saying money...? I can't remember, I don't think my money count increased after talking to them so I don't know) - Ended up just going to one of the fast travel signs and bypassing the "I'm not going to steal" thing.
Just some issues I found - Keep up the good work on the game :D
