I have a problem getting the details of the new type of ranked: TEAM_BUILDER_DRAFT_RANKED_5x5
I tried to getting the details this way:
riotClient.Match.GetMatchById(server, game.MatchId);
// Server: RiotApiConfig.Regions.EUW
//MatchId=2505961084
the problem is "JSON serialization error".
Anyway you have a great API here, good job ;)
