Was having an issue with the solar farm myself. Had Trade port set to "Use Locally", but once I started sending Plastic, alloy, and processors to the Solar Farm, the Processor factory stopped getting platic and alloy, it was sending EVERYTHING to the solar farm. Once I disabled delivery of Plastic, and Alloy to the Solar Farm everything went back to normal. I'm thinking focusing on one material at a time to a great work might be a safe bet until a fix is issued.... I mean IF a fix is issued.
