I have tested the OP security and it doesn't seem to work.

When I set an OP to :
_ Attack not clan / GR clan : only clanned people can GR in and go in UG (which is normal)
_ Attack not clan / GR friend : ally can GR in the OP but they can also enter the UG which is not normal.

Please fix this security because I need to set security to allow people to GR to my OPs but I don't want ally to enter UG since some of them are enemys.

Thank you
