The game not always shows heroine's name correctly [shows the default name]. Spotted in Dimitri route [when they are having dinner], in Neil's when Angela speaks [dunno where exactly] and when you have to make dresses for events. //the older ones I think? Tho I might be wrong - and if I am, I'm really sorry, I did read it at 2.00am so my eyes might have deceived me.
Also - sometimes when you buy something, everything else disappears. If you leave shops and go there again it fixes, tho.
