I know this is just another one, but i'm a private modpack maintainer and in updating our 1.6.4 modpack and uploading it to server which also included updating forge to 965 from 953. We are now getting the bad login error whenever we try to join the server and the console says nothing helpful towards trying to solve it.

This wasn't happening before the modpack update and now it is after the modpack update; any ideas why its doing it?

The other admin who is building our next pack, uploaded the one he is currently working on to the server and it doesn't happen; so something is wrong with the pack when i updated it and i don't know what as forge & 90% of the mods were updated. Making it "impossible" to try and figure out what, how and why went wrong.
