Vanguard patch notes update August 11 : Dev Error & fixes

The developers at Vanguard Sledgehammer Games continue to update the game and bring players new content.

Players will no longer have to deal with DEV ERROR 10308 that occurred on the USS Texas map.

Vanguard attachment exploit fixes

It appears that an unintended exploit allowed players to combine attachments from other weapons to achieve combinations that shouldn’t be possible. This would result in overpowered weapons going haywire and the devs were quick to nerf the issue.
