The root cause of the Fortress Battle account lockout bug has not been fixed! It happens every event
This is not ok. Really not ok.
Every event, a new batch of players (as well ones who know better but were not careful enough) gets stuck locked out from the game, because whatever is causing this wasn't actually fixed after the first time, and still hasn't been fixed 3 or 4 events later!
Also, there is no effective or timely in-game communication from the company, or ability to disable the feature (all fortress battling, not just the bus, but just the bus would be a huge signal flare at least) so that players stop getting stuck.
Seriously, take whatever time is needed to actually figure out what is happening and how to stop it. Cancel events if needed. At the very least, if even remotely possible, release an emergency client update that would let us keep playing the non-fortress parts of the game instead of crashing!
And do Not resolve this bug report until the actual root issue is fixed, not just the current event, but so it won't happen again in the next one. It's not a duplicate of the current event's thread either.
