When a custom model is added using AddSimpleModel and used in a Create(Dynamic)Pickup, the pickup is displayed as the invalid yellow question-mark model.
If the SA:MP Addon (samp.asi) plugin is present on the client, the same pickup works correctly and shows the proper model, without any changes to server-side code or model registration.
