Issue still actual

I also thought this was fixed for a while at the end of last week, but it turns out that there are still issues. With that said, I do think it's working better than last week.

If I recall, last week, any call to /lor/inventory/v1/cards/me or /lor/deck/v1/decks/me would always result in a 503 - Service Unavailable.

Since then, that has changed. Now, it seems that lor/inventory/v1/cards/me does work, but not the same as it used to. Maybe I'm misremembing, but I'm pretty sure the RSO endpoints should be able to be accessed from any "server" (americas, sea, europe). And it was recommended to just access the one that is closest to your server. Now, it is required to access the server of the player you are requesting info from. This means accessing the cards endpoint of cards for a player on the Americas server from https://americas.api.riotgames.com/lor/inventory/v1/cards/me will return the cards correctly, but accessing the same player with europe or sea results in an empty array.

The /lor/deck/v1/decks/me still always results in 503 - Service Unavailable.
