So I joined a raid but after I tried to enter the raid this message keeps popping up. "You have entered too many instances recently"
I have done 1x Love is in the air boss and then been afk i dala for like 3 hours doing professions and searching for raid grp.
If it's functioning as normal, it's not a bug. Players, or rather their singular accounts, are limited to 5 instances per hour.
That limit is quickly met if you go in and out of instances for resets and 10/25 mode switches.
Only solution for that is to wait. Reloging or reloading or restarting the game has no effect on it.
