I think I found an issue when using Pathauto and Redirect modules.
I configured Pathauto that way : when I edit a node title, the node Pathauto alias is changed and the old alias is deleted.
Redirect module catches the old Pathauto alias and generates a redirect.
with node/6, old alias is "level2-1" and new pathauto alias is "level2-2".
When I create a new node (example node/9) with title "level2-1", Pathauto creates the alias "level2-1" automatically.
But, the redirect "level2-1" to node/6 still exist.
And, when I go to URL "level2-1", I got node/9 and not node/6 like it should be (the redirect "level2-1" to node/6 is still present).
Did somebody already met this issue ?
There may be two possible solutions :
* Either the redirect "level2-1" to node/6 should be deleted
* Either the new pathauto alias takes into account the existing redirect alias ("level2-1") and generates a derivated alias ("level2-1-0").
Thanks for any idea or solution.
