Currently we are implementing some streets for our city builder game.
I have the following problem:
I created a tile, put the skin on the tile and created a supertile and put the tile on the supertile. My attachment point for the tile on the base grid is the right edge.
The whole street is walkable except for one tile:

this tile is not the attachement point. The avatar is always standing behind it.
I can't select this base grid tile in the editor anymore once I added the street to the supertile.
All other points of the street's base grid are working fine, the avatar is walking over the street, except of this single point.
What can I do to fix this?
Should I attach the tile somewhere else on the grid?
Is there any option I missed in the editor?
Thanks a lot for any help!
