Hey, really great miner, i use it since 1.5 and i'm very happy with it
Best miner so far for any AMD cards i've, R series and RX series.

Recently i've downloaded the new 1.6.5 miner version and tried to add the nicehash additional parameter to my pools.txt file but it seems to not work correctly.
Everytime i try to add the nicehash parameter, the miner can't found correct pool configuration.

pools.txt file Like this:
{
  "pools" :
  [
     {"pool" : "pool_1_address", "wallet" : "pool_1_wallet", "password" : "x", "nicehash" : "true"}
  ]
}

Any idea what's going on or what am i maybe doing wrong ?
