I'm seeing double of everything in Anvil. Still have to check if its true for other cities as well.
Symptoms:
Double signs
Double gates
flickering textures
some good lag

I was also wondering how many mods contain the Anvil Bay Expansion? And what those mods are? I'm seeing double NPCs (that were added by the Bay expansion) Thanks.

(Also, on an unrelated note, I can't get the Better Redguard textures working. I'm using Roberts Male, and the necessary files for that body from BR. Body is dark and head still remains that pale vanilla color. hmmm)

I think you are doing double duty with the OC plugins.

Either use 78 or 79 - not both. Been a while since I've used OC but I'm pretty sure that using two both say full is not a good idea.

in other words - stop hurting yourself.

Don't do that. You're doubling everything in every city that way, and I can't imagine Bravil *OR* Leyawiin looking all that useful in this condition.

Also, OC is what added the Anvil Bay stuff. But that's coming out when I get around to packaging 3.5.

Oh yeah, I was just identifying the double doors using FormID finder, and that's when I stumbled across my mistake.

Thanks though.

Five that I know of:
Anvil Bay Expansion
Open Cities (until next release)
Open Better Cities
Better Cities
Hillsborough Estate (or so I believe I was told a while back - never used the mod myself)
