Ok, long story short. We all know the friendlist is kinda bugged. Having to reboot the game multiple times to even see your friends online, let alone invite them (or see the incoming invites).
We encountered a new one…
For 3 day’s in a row we have a friend who cannot join our games. It’s like he can’t send invites, or receive them from specific individuals. We literally have to invite other people who aren’t affected, to play together. But it is impossible for 3 day’s in a row (more than 20 attempts) to play together without an external player getting us into the same party.
If we manage to avoid the regular bug and see each other online, we cannot invite each other into the game. I don’t receive invites, he doesn’t receive them either.
