Yes some thing is wrong with the payout script I only got 0.6 VTC of 2 listed. I do not have that high hash rate my self thats why it's on net 3.
I'm stoppping the payout script now. No more payments until I can see what happends and fix it.
I recommend switching to an other node until it's done or user port 9174 for non merged mining (VTC only) you will get shares the normal way and it will take time to work up to excpected again.
