[FSOD] Custom Items won't load up

Sooo i changed my custom items from additions to dat1 since other players lagged on my server.
I changed the ext=true to type= e.g: 0x0dc32
After that I rebuilt the solution, decompiled the client and exported the first binary data (ghost ship). I replaced the code with the dat1.xml and put it back in JPEXS.

When i stared my server, no custom items won't load up. There just stands "art" and I can't even use them. Idk if I made any mistake but i searched for them and found nothing.

Help is appreciated, thanks.

try changing it to a lower integer, or try and replace the ID with an ID a prod item has like t14
