i had the db error thing pop up on my wallet after restarting the client. I first did repairwallet through the console window, it did indeed find a spent coin mismatch, then I shut down balls client and restarted using -rescan as a flag in the shortcut. the error returned so i deleted debug.log and db.log restarted with the -rescan flag via shortcut and then the message went away along with the checkpoint error. so far been 30min no issues.
I did all this and all seemed fine for awhile but the error came back. When i got stake i decided to test "repairwallet" command and it found a mismatch which was the same amount as the stake. Now everytime i use repairwallet, it will revert my account balance to what it was before the block count reached 360K.
I have also tested to send coins to another address in same wallet. I sent 10000 BALLS and the wallet says it is over the size limit and i need to pay 6.4 BALLS transaction fee. Even 1000 BALLS is over the size limit.
