When an ally summoner reconnects, it doesn't show their summoner name. I believe this is a bug even though some anouncements were changed in this patch because in chat, it doesn't say "<Summoner Name> has Reconnected", instead it just says Reconnected.
[GAMEPLAY][USER INTERFACE][CHAT] Do you remember more details about the game in question, specifically what champ(s) had this issue? If there was the same champ on opposing team or the champ in question was Alistar, or Garen, that would be something to work with. Also if there were simultaneous disconnected players that would be a possible link between my game and yours.
I just experienced No-Name Reconnect Text bug for the first time in Intermediate co-op SR. The champ in question was either Alistar or Garen . Nothing seemed special about their names, besides sequential numbers in one of them. There was also an Alistar on the other team.
There were no other bugs I noticed this match.
It's not a gamebreaker,but it is a
