custom item crash

[Hokku]

Hello!
Im getting server crash with a items when adding it to my client, its a new tp like a magic forcefield,
just added the sprites and created the item with object builder (havent added any propiety here) and here is my item editor and items.xml.
I got a problem with a gem that i added too, it was a stackable and it crash the client too, have no animations, so i think is not animation bug.

EDIT: Forgot to say im using 10.77 with Tfs 1.1.

item editor

Spoiler

items.xml

    <item id="24369" article="a" name="teleport portal">

        <attribute key="description" value="You can see the other side through it." />
                <attribute key="type" value="teleport" />
        <attribute key="effect" value="teleport" />
    </item>

I think you will also need to build the item with object builder and save that into the client.
