Hello, thank you for letting us know; this has been fixed in update 1.0.1.

Changed Status from Pending to Fixed

Changed Fixed In to 1.0.1

Please also download Custom Item Definitions version 2.5.0; I just released the update.

i get another error now . Error while compiling AnvilUpgrade: 'CuiInputFieldComponent' does not contain a definition for 'PlaceholderId' and no accessible extension method 'PlaceholderId' accepting a first argument of type 'CuiInputFieldComponent' could be found (are you missing a using directive or an assembly reference?) | Line: 2554, Pos: 71

I updated it under the same version; please give it a try.
