Found the red diamond error and discovered it was an empty bottle of scotch not appearing in the game. Is there a way to fix this?

Missing meshes probably. I'd advise to verify integrity of your game cache on Steam.

Before verifying cache, go to fnvedit, load up all mods, locate the file entry for scotch bottle and check the mesh. If you have a mod effecting large scotch bottles like a clutter of bottles mod that is missing it's mesh, it won't necessarily be corrected by validating cache.

Load order? Sometimes this happens if you have too many mods.

@IRORIEH I was just thinking of simply removing scotch from the game via GECK but I'll check FNVEdit.

@Wertologist I'll have to check in a few hours because I'll be at work.
