I got some weird collision issues today while I was working on a new Tile Map.
There is one plain blue tile I selected as an obstacle within the collision group (painted as red on the editor) of the associated Tile Source.
Now my character is colliding with every tiles (the ground itself, anything…) unless I move this blue tile outside of the collision group !
It might be something related to Tile Map layers, as no collision works for any tile in the lowest layer…
Do someone knows if there might be an issue with the collision group ?
