While Treyarch may have only just released one patch for Call of Duty: Black Ops that doesn't stop them from working on the next one.

Unfortunately no game is perfect and issues arise but thankfully for loyal Call of Duty: Black Ops fans Treyarch are working hard on resolving them as quickly as they can. Last week we informed you about a new patch that fixes some existing problems but now they are preparing another patch.

The new patch fixes issues raised in the official forums for the game. Treyarch confirmed today that the next patch will fix several currently known issues including the following:

• New issue - "an error occurred while connecting to the server" – to be fixed in an update ASAP
• WMD map hole – Fix incoming 11/30
• Zombie gas clouds sticking around – Fix incoming ASAP
• Disappearing zombies glitch – Fix incoming ASAP
• Variable zoom scope will not stay zoomed in – Fix incoming ASAP
• Sierra button layout for Classic Controllers (CC/CCP) assigns same button for Tactical Grenade as steady button for scoped weapons – Fix incoming ASAP

As before you will be prompted to download the patch when it is available when you try and play the Multiplayer mode. If you are running Single Player at the time switch to Multiplayer mode. It also cannot be accessed through Zombies mode.
