Changing item color, inventory image

[Damascus]

I seem to continually be running into this "original file conflict" when trying to create a second item, how in the hell do I get around it? Here's what I'm doing step by step:

Spoiler below!

Open "coins_small.ent" file in Model Editor
Import mesh -> stone_small01.dae
Change dimensions of body
Change variables (Make it a grab object)
Save as "fulm_gold.ent" in "custom_stories/Festung/entities/gameplay"
Place random item in game from dropdown list (crowbar in this case)
Change .ent file loaded to my "fulm_gold.ent"
Change internal name of object

Still, no matter what original .ent file I use, it refuses to show up in game. I have no map_caches.
