I am aware of the coat room/trader hallway fog glitch, and am looking into how to fix that. I think it is a zone portal issue, but the fix will be in the next release.
I have also noticed that the spawn points for the players need to move as they are currently in a bad location if you die mid round. I am considering moving them to the central room but am open to suggestions.
As for the lighting, I agree that I went a little overboard with the KF mood light thingy. I am unfamiliar with most of UEd 2, and was trying to get only a little fog...which went totally wrong. For whatever reason, I can't seem to get the fog to be gradual, and having the same color fog is boring. But, I think changing the reds and greens to be more soft colors such as orange and a yellowish green may be a good alternative.
I have also noticed some of the trader rooms in the basement do not light properly. These will also be fixed in beta 3.
I am also aware of the patriarch misspawn, where he doesn't always spawn from the central elevator. This too is being looked into and fixed. Beta 3 will also include more spawns for monsters, including crawler vents. More deco will also be added to remove the 'empty' feel.
With that said, has anyone noticed any glitches/exploits? Or places that are way too easy to camp? I would like to fix these for the next release if possible.
Thank you for the feedback, it has been most useful. =)
