[PLUSEMU] cant load catalog item

[Iluminatos]

Hi, something really odd just happened.
Im sitting here and editing names on my catalog_pages. Notice im not touching catalog_items neither furniture tables AT ALL.
After a while i decide to restart my emu and then.. this message pops-up?

The item ID for 1353 is existing as rare_dragonlamp*6

Why did this happen? Please help me out.

Read the error. "An item with the same key has already been added." What do you think that means?
