Mistakes After Accepting Invites And Unable To Invite Specified Player Errors

[Mactax]

To be honest I'm pissed. After being back from summer I keep getting the mistakes, when I want to invite someone or someone invites me. The funny thing is, when I try to invite someone, for whatever reason, it actually does invite 1 out 10 players . I am sure, that nothing in my PC or internet has changed. Considering the overall emphasis of the recent changes on the forced group play (Survival missions and Lephantis), this bugs are even more infuriating.

The worst thing is, Warframe is not the only game I play online. League of Legends, DotA 2, World of Warcraft, Guild Wars 2, Dark Souls, Borderlands 2 - there are no problems with these games, I played all of them for the last 2 weeks.
