Usually I find the following sequence occurs with Midnight at busier hours (though not just peak). 1 log in start up and everything works fine for a bit then a time out. 2. Restart the program, login and start it and Midnight crashes to desktop. 3. Restart the program again wait for the you are already logged in prompt to not appear and then everything works fine.
I've suspected its an anti-virus program problem with where Midnight/light stores data (temp folder?) during use but I've not bothered to look into it much further as this is just fine by me.
As for mass banning, I'm still in game. Be smart how you use it and where.
