Suggested fix (unconfirmed): Talk to Mary in the evening to trigger the option to go buy the dress. Continue advancing the days to find Igor later in the story.
The problem
As you can tell by the title, I'm at the point in the game where I have to buy Mary a Dress (she already told me about it) and I need to keep following the cop but first I have to find igor. I might be stupid but I cant find either Igor anywhere or buy the dress. Also Im a native German Speaker, sorry for my bad English.
Suggested fix (unconfirmed): Verify game files integrity via Steam and update your graphics drivers. If language localization is bugged, switch the game language back to English.
Suggested fix (unconfirmed): Press Shift+G while the game is loading to open the Ren'Py settings menu. Change the display settings until the visual output appears correctly.
