in case anyone has run across peculiar behavior with the esp8266 modules that has a puy/puya flash chip it seems the espeasy people have had issues too and say a fix is on the way ( for their software at least)

PUYA chip is a little special in the way it does "updates" on bit differences.
It should behave normally for standard sketches, problems occur when using spiffs or fake eeprom/flash read/writes.
