If you move your coins, you will reset coinage. I’d suggest you make a new address and simply send your wallet balance to that address. Note that you’re gonna pay a boatload of fees for all those inputs (probably less than 10 nsr).
How do you have nsr at 30 different addresses? Are you sure it’s not at 1 address with 30 different outputs? The wallet autochunks nsr into 10,000 nsr groupings.
