Recently I've been working on a mod, and somehow inadvertantly I caused a bug that makes it so shivering Isles meshes don't show up when the esp is active, sometimes they are error markers, and others they just don't show up at all. I accidentally fixed this problem once before in TES4 Gecko, but I don't remember how I did it. The only cause I can possibly think of is that I have merged a number of pre-Shivering Isles plugins to my main esp. It seems like this bug can't be that uncommon, since I've had it twice before. Does anyone know how to solve it?

You fixed this problem before and you didn't make a note of how you did it? That was your first error imo. Always make notes. Always. I've made mistakes too with my mods but luckily I've always kept notes of why things can go wrong, and I'm glad I did.

In regards to your specific issue, I can't really give an answer as there isn't much to go on. Maybe give some more info?

What info would you like?

And when I fixed it the first time it was inadvertent. I was working in Gecko deleting an un-needed Worldspace and the refs that went with it, and when I got back in game the SI problem was solved.
