It effected everyone in the server. Lighting was super bright, and for some reason the grass texture was black.
This happened on most of the maps in rotation. After disconnecting, and later coming back on to play on a different server the maps visuals were normal again.
This is not a local problem since it was a shared experience over the entire server. Has anyone else encountered this? Hope Crytek notices and fixes it soon
