>Anyone else having this issue or have any idea of how to fix it?
It happened to me a couple of times, 3.3.2 and Bittrex.
It seems to happen when the first order is PARTIALLY filled, then :
* gunbot checks the wallets and don't see any bought value (because it shown 0 until the order is filled)
* then he thinks he didn't buy and places an order again.
Don't think there is any solution apart trying another version... good luck...
