I just got this error message today out of the blue:
Assets/PlayMaker DataMaker/Json/Actions/ConvertJsonStringToXmlNode.cs(96,18): error CS0433: The imported type `Newtonsoft.Json.JsonConvert' is defined multiple times
Attached image is the message it gives me when I hover over the line giving me the error.
Already tried updating Datamaker. I don't use the action so I'm just going to delete it for now.
