First, I've checked the forum, and read different posts about this topic, but I'm still not sure how to proceed.

My mod has 3 deleted navmeshes in two exterior cells. After going to the Data screen for my plugin and checking the IGNORE flag to re-activate them, I've noticed the meshes in question are duplicates of existing triangles, ocupying the same space but with different IDs. What should I do now? The triangles are pretty out of the way (on a cliff's border, between unpassable rocks), so I don't think leaving them will affect NPCs that much. Would that work, or will the fact they were deleted in the past (and now are duplicates) have other negative effects?

Before I forget, Arthmoor mentioned in another thread that if the IDs started with something different than 00, they could be deleted without problems. This is not the case here.
