$(GROUP) in the download path return the parent folder and not the folder the post is in.
Basically $(GROUP) yields the same text as $(GOG)
I have my download path as F:/Agent/$(GROUP)/
I have group "a.b.mygroup" organized in the parent group "Unsorted"
My file downloads to "F:/Agent/Unsorted" instead of "F:/Agent/a.b.mygroup/"
