I am using the "05m_PoorHouse_A_Platform_Stairs_4_A_item" which is from the original game but the AI does not recognize that you should be able to walk on it. It is always displayed as red after recalculating the AI Grid.
How can I make this work?
Make sure in the side-war ([X] Is walkable) is checked if that still doesn't do it then maybe those stairs are not meant to be walked upon ;P
