Just tried signing into the game and I encountered:
1. A waiting timer telling me that I had over a minute to wait.
2. On getting past that point, I saw either:
a) a black screen with just the exclamation telling us that server transfers were on hold - nothing else was visible OR
b) I got into the main client but there were exclamation points besode each of the game modes.
c) an error message saying that an unexpected error had occurred and told me to re-sign in.
Between this and the critical error bug that still is lurking in the background, it is getting harder to play and enjoy your main game Riot. Can you please let us know what is going on?
