it might work if you put a floor there between those two stairs when you go into custom. Then put the gozas there when you come out of custom, raise them up a few tiles. Go back into custom and delete the floor tiles, then lower the gozas down so that they are level with the stairs and you can walk on them. Hopefully that works, sometimes if an item is next to a tile it shouldn't technically be able to be on it MIGHT put it into the crate, I'm not sure if it will do that or not with the goza right next to a doorway like that or not.
