Can somebody please help me understand gas usage and refunds. In all of my SC calls I see a red warning - (example) "@too much gas provided for processing: gas provided = 59931999, gas used = 2210209" And at the same time "Gas Used 59,999,999" In other transactions that I saw in explorer I see that network sends refund of unused gas back to user. And it is written in docs that it should do this. What am I doing wrong?
