I'm not sure if this would be an issue or not but I ran HCDU and came up with many possible conflicts. It's just objects, but I'm not sure if store objects messages would have any issues or if this is just a false positive. I've included the log as an attachment.

It looks like you downloaded both the individual item and the full package of all the items.

Do you by chance see 2 of each item when you go to place them?

No, there is only one of each item in the catalogue.

Well try this, make a throw-away hood and remove your CC that is listed in that error report and then delete the cache files start up the game and then exit.

Now put in just the collection and see what happens, see if it shows up in this test hood.

Ok done and done. The objects are there. I don't know what's the difference between them or why there was duplicates in with them. The only conflict that remains is the deco_armoire conflicting with lord darcy's fixes.

The one's that say lord darcy's are the item but they been fixed for later EP's, those items came as single item or the complete set and you had both and now I see you have all 3.

1 item as single.
2 item is the complete set of all the items from 1.
3 lord darcy's fixed items from 1.

All 3 are the same item but lord darcy's are the best.

Good deal I also noticed that after removing the duplicates the game loaded a bit quicker. Is there any way to figure out the difference between the duplicated items? Thank you for your help.

There is no difference between the items per say but for lord darcy's were fixed to work in all EP's.

The main difference between 1 and 2 is that 2 is the complete collection all in one download and 1 is each item as a single download.
