As soon as I press OK to publish, the editor freezes for about a minute, then a message says: Battle.net connection was interrupted, and the Publish Document window tells me: Unable to send event to Battle.net. I will also now be logged out of Battle.net.
Sometimes this will be all, other times I will get Document dependency header file is not available errors and I will have a file transfer open with my map uploading but stuck at 0%.
