Previously, I posted about how we on server 80 could enter the Chaos VS event, but did not receive rewards after it ended.  Our situation has changed. Yesterday, 27 April at 20:47 server time, we were all disconnected from the server for a few minutes. Today, 28 April none of us were able to enter the Chaos VS event. We all got the "Please try to connect after 5 seconds!" error message when we clicked the Join button.
