This means that Vanilla servers are now utilising the database cluster which we've introduced over the last month or two in RHS.

The two main servers this affects right now are:
AU#2 Light Vehicles Server The new APC's from the new DLC is added to this server. Pawnee's, and other light attack aircraft are back inplace Vehicle Limits are in place, to stop one team flooding out Armored Aircraft against the other team. US#1 24/7 Day Server All new tanks are added to this server. With the new change, everyone is back to level 1, but along with it, everyone's starting on an equal footing for the first time in years, as well as the fact no more profile restores, and lost profiles are going to happen!
