[Unsolved] Items

Hello everyone, in my RPG i was testing out a quest, and i had a problem.
There was a field of Cattail(Doodads - Environment/Terrain)and you had to collect 4 Cattail. I took the Shimmerweed item and made a custom of it, copied the custom model name for the Cattail and pasted it on the Shimmerweed models area. When i picked it up, it didn't go in the heros inventory. It just dissapeared, can someone help me

The "f)" is there because i was in WEUnlimited, but yeah, you should be able to find that field no problem.
