I often read about the “Failed to join requested game” error, friends had that a few times, and I think me too.
Now we have a particularly hard case.
My suggestion:
Expand the Message, so Error seeking can be narrowed down.
WHY did the joining fail.
I mean the game must have some sort of break that tells it why it stops, so you can easily relay that to the player. That way the problem can be narrowed down for bugs, and also can be easier fixed for those encountering it.
After all, its a thing of relaying text to the player, should’t be too hard, right?
