It just keeps NOT doing 8 rounds, doing 1 instead, then starting over and charing me fees again... Eventually, the wallet will be empty from fees.
This is exactly what was happening to me prior to .31 - I had recurring fees with seemingly no actual denominating happening past 1 round. It seems you are still somehow affected by this bug.
Once I updated to .31, coin control showed that those rounds I paid for were actually successful, so I don't believe those fees are going into the ether.
