Hello, I have an interesting issue involving three different installations of platformIO. Only one of the installations allows me to successfully build a project on a Wemos D1, the other two have library failures despite copying over the entire project directory of the working build. Each of the three installations have identical platform.json files located under .platformio/platforms/espressif8266 (used a file diff utility to verify this) Here are the file contents:

I was told by an experienced member of the community that SoftwareSerial.h is part of the core and shouldn’t create any problems. There goes that word, shouldn’t
