Passing along a message, since I just got in contact with GTO.
The Devs are aware of the issues with Apprentice and Blitz, but they are very busy with real life currently. There are plans for changes to the servers in the future, but these aren't 'quick fixes' - and I'm not 100% sure if these will be the fix to the problem, or if a quicker solution will be used until the changes to the server.
Basically, the issue is known, it is being looked into, but no specific date for a fix is currently set. Please do not report this as a bug anymore.
I do not have word on if it's going to be a rollback, restart, or what after the issue is fixed, that will be determined later. I just have word that the issue is known, and being looked into - again, there is no set date for a resolution.
