So fix problems didn't find anything. But I few times I have gotten a message when saying saying that something minor is messed up and sketchup will fix it.

The rogue components aren't anywhere near other groups or components, which is why I didn't see them pop up at first. The component origins are close to the geometry, and there aren't any pieces of things in the component (that I can see at least) out in the distance. However, the model is miles(literally) away from the origin point in sketchup (due to the need to maintain the origin from CAD.

I do need the original components (they are landforms modeled in another software), and for now I've deleted the extras and purged with no catastrophic results.
Hopefully they don't come back, but since its happened in 2 files with completely different components, I'm trying to get the bottom of this before it happens again.

Thanks!

I have been working on a very large and messy file (actually a set of messy files that will be combined into a master model). In at least two of the files I have discovered 30+ identical copies of one of my components (only with the new name SKP2D_1,2,3... etc)in the same location, way way off from the origin and the rest of the model. I've been having issues with plugins and have recently deleted all of them and started fresh. But this appears to have happened again. The plugins i have been using with it are 'extrude edges by vector', 'drop at intersection' and 'copy along path'. The files also bug splat nearly every time I try to drape, even with simple stuff.

The file was originally modeled in a combination of rhino and inRoads, so it can be unwieldy at times, even with basic commands.

Has someone else encountered this?
