Ubi Soft is, by all accounts, having a bit of trouble with Raven Shield and its patches. Having released the 1.3 patch on June 17th, the game's official forums were set ablaze with complaints of the patch breaking CD-keys and servers. Ubi now reports that the development team has been able to reproduce these issues, and is working on a patch. For the patch.
Meanwhile, they have another patch in the mill - 1.4 - which is set to fix... even more bugs! The team has tweaked the netcode to include fixes for reticule lock, the zoom function staying active, a grenade bug, and players getting stuck in ladders. Well, we're sure they know what they're doing, even if we don't.
