Selecting Moscow realm and ending up in Frankfurt realm ?!

After the update, selecting Moscow realm doesn’t force realm and 90% of the time it ends up loading zones in Frankfurt realm.

If one individual gateway is at maximum capacity, the game will offload you to an alternative one instead of placing you in a queue. This is intentional, and not something you can choose to override. If the fallback gateway being chosen for you automatically is a poor choice, you can try manually selecting a different preferred gateway to play on neither Moscow nor Frankfurt.
