I figured out how to get past the clan glitch for those of you still having issues with inviting people. The fix that was applied only applies to clans created after the date the patch was applied. What this means is clans created before the fix will have the invite bug, while clans created after that date won’t have that bug. The only known fix at this time is recreating the clan.
I don’t log into the forums much but I thought I’d spread the word around for people still struggling with this. It was an issue for me for a good while because I couldn’t join my friends clan until I got the idea to try that.
