Cannot complete allies quest

[Belhamel]

The allies quest cannot be completed for some reason but i did ad two friends an really long time ago (but not before the quest was visible). How is this possible?

As it isn't that difficult to send out friend invites, could you just send out another one to complete the quest?

I could try that again yes, already did that 1 time.
