[eSports API] Bug With Players That Have Changed Roles

I noticed an issue with the LoL eSports API ( http://na.lolesports.com/api/swagger#!/api ). Players like Nien and Overpow who have switched roles only show up as their current role. This is even the case for the gameStatsFantasy operation which returns data from past games.

So for example, when requesting stats from the 2014 NA LCS Summer Split (tournament 104), Nien shows up as an AD Carry for CLG when he was actually playing Top Lane.

Here's what I'm seeing for one particular game: "game3109":{ ... "player176":{ "playerId":176, "kills":2, "deaths":6, "assists":4, "minionKills":254, "doubleKills":0, "tripleKills":0, "quadraKills":0, "pentaKills":0, "playerName":"Nien", "role":"AD Carry" } } ... }

Is there any way this could be fixed? Does anyone know another way I could get the player role information? Thanks.
