I am using:
UR 7.x-1.0-alpha4
INVITE 7.x-2.1-beta2

I am having what I believe is the same or similar issue as in:
in that
--user A invites user B to the site,
--user B registers and confirms friend request on the registration form,
--user A and B are not friends after user B submits the registration.

Seems like the patch discussed here (http://drupal.org/node/1345694) is already incorporated in to UR 7.x-1.0-alpha4 (however I do not see (
@@ -75,7 +76,6 @@ function user_relationship_invites_invite($op, $args) {
) but it is not working. Or I am doing something wrong :(

Any help is appreciated.
