I’m not entirely sure if this is a bug or if it works as intended so I apologize in advance!
The developer product purchase prompt remains open when the main menu is opened (escape key is pressed), however when trying to open the main menu with a controller (start button) the main menu will not open. This happens every time I test it and I’m assuming that this is something that happens for everyone.
I wonder which behaviour is the incorrect one. On xbox the start button not opening the main menu could be a problem as a malicious developer could spam purchase prompts to stop a user from leaving the game. On PC it seems more intuitive that escape would close the prompt purchase gui rather than open the menu though.
Purchase prompts should appear underneath the escape menu. It would be somewhat silly to deny a purchase prompt immediately if the escape menu is open.
