Minor issue with multiple instances
I'm following the instructions for running multiple instances, but am having an issue with the most recent pull that was working ok with v3.1 Release.

In first copy of v3.3, I setting config with:
    "GPUCount":  2,
    "SelGPUCC":  "0,1",
    "SelGPUDSTM":  "0 1",

Make second copy and setup config with:
    "GPUCount":  4,
    "SelGPUCC":  "2,3,4,5",
    "SelGPUDSTM":  "2 3 4 5",

Starting the first miner, gets the 1st two GPUs going fine.  But starting the second miner seems to reset the following in the 2nd config file:
    "SelGPUCC":  "0,1,2,3",
    "SelGPUDSTM":  "0 1 2 3",

If anyone has this working in v3.3, or know a workaround, it would be much appreciated.  My miner won't run stable without two instances due to mixed cards in rig.

Thank you
