Hello, have you checked the logs for any errors/warnings on the packaged version? Also, I think you should post some screenshots of the blueprint that handles the opening/closing of your inventory.
Hello,
I have the following problem for a week and Im unable to find a fix.
My Inventory System works fine when I play the game in the editor (by clicking “Play” or pressing Alt + P)
But when I package the Game and open the Inventory it wont close (both development and shipping have this problem). The Game keeps running but Im unable to move or click. (Its also very hard to test because I have to package every time)
Please let me know if you need more/better screenshots or any other form of information!
Thanks in advance
