Oh man. I am lazy to do that. But I still think its a bug cause I had it long before I installed any mod.
Rule #1 when troubleshooting a TES game: if you have an issue, and you have mods installed,
always remove your mods first to see if the problem goes away.
This isn't rocket science. When a patch comes out, especially one like 1.4.27 which directly messes with the launcher and mod load order, chances are good it is going to break a mod or two.
Take out your mods. See if the problem goes away. If it does, there's your answer. If it doesn't, at least now you know the mods aren't behind the issue. FWIW, I'm with Kastagir...haven't seen this issue reoccur with the latest patch. I only use a couple of texture (non-.esp) mods.
