# IMPORTANT In order to enable proper mapping of metaverse local data set and remote data set, it uses following package to generate unique ids called guids: . The package does the job, but a have potentially dangerous behaviour that may almost forever unlink the feature from remote data set, which in other words removes all real-time changes made, i.e. an image of an NFT with link on OpenSea may disappear

This only happens when somehow Reset method was trigger on this component when you are working on your project in Unity3D, because apparently guid is regenerated everytime the component is resetted

So, please, be carefull when you are working with it. The same function also is triggered everytime you reset a prefab in case if GUID component is attached to a prefab. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
