You are not setting the item by reference. The datatable will also reset upon the end of gameplay. It does not have a built in load / save function. You would have to use the datatable function convert struct to JSON string and save it as a field in your savegame. Though loading would probably need c++ > [@Is there a way to update and save data table from blueprint?](https://forums.unrealengine.com/t/is-there-a-way-to-update-and-save-data-table-from-blueprint/104390/13): > > the engine now seems to support load/save to csv/json this is available on 5.1 at least but not sure if it’s on previous too. also You can save your data table from cpp. call FDataTableEditorUtils::BroadcastPreChange(DataTable, FDataTableEditorUtils::EDataTableChangeInfo::RowList); you can get the rows using DataTable-\>GetAllRows and you get some pointers. you can modify them. or you can add rows using DataTable-\>AddRow at the end you need to call DataTable-\>Modify() then UEditorLoadi… Though I doubt there is need for a datatable for the characters inventory. You can just save out the TArray of structs to a save file and reload it on game load de-serializing it and populating the array again. --- _[View the full topic](https://forums.unrealengine.com/t/data-assets-and-an-inventory-system/1422623)._
