When using more than one NCF to mine (2 usually), they will both mine fine for a few minutes, then will stop with the NCFs themselves giving pulsing green (indicating a problem). The NUHOL remains the normal amber/orange color, and has ore detected. Only way to clear this is to turn off the NUHOL, wait a minute then turn it back on each time that the NCFs go to pulsing green. Using only one NCF to mine works fine.

Any suggestions? Thanks!
