I have a group of friends I play with quite regularly. We’re not very good, we’re bronze-gold, so we don’t get upset when we lose as long as we have fun. However, I tend to get annoyed when they just stay behind and not use any util or not...

Every time I try to add someone in game, it just does quite literally nothing. It will just make the adding noise but wont actually add them, i’ve tried restarting it but that didn’t do anything, any suggestions?
