FWIW this bug seems to be present in both official NerdMinerV2 firmware and other "closed source" forks (assuming they reuse a lot of this code). Many different ESP32 based devices are submitting very low difficulty shares even though they have received proper diff from the pool. In fact, a rejected share can come in the middle of several hundred accepted shares. For whatever reason, every once in a while, it just sends something in crazy like this.
This also goes for dupes:
