Two short questions about using icons:
1. I tried to work with an icon editor called xiconeditor.com for example and others but I get always the same bug message: https://www2.pic-upload.de/img/34762212/Unbenannt.jpg Although it is a .ico file and in the correct size (32 x 32) it does not work - why?
2. Before players get to another game chapter in my adventure all icons should dissappear. Is it possible to delete all items at one time and if, how can i reach this?
