I believe that I could possibly have lost around 5k grins because of a bug in the test net. Yesterday I was messing around with grin commands and trying all different things, when I’ve realized that after canceling a transaction, my locked funds didn’t return to my wallet and were gone forever. Here is my current wallet txs and wallet info, 12 hours after the bug: [https://pastebin.com/QBARnzpR](https://pastebin.com/QBARnzpR) (I believe the bug happened at transaction 178 - line 364 of the pastebin) And here is all the grin commands I’ve run in the session that the bug occurred: [https://pastebin.com/69Ge0Pbe](https://pastebin.com/69Ge0Pbe) (Bug happened after line 743) Another thing I’ve noticed, is that yesterday some transactions I’ve tried to make returned this error, even though I had more than enough “currently spendable” grins in my wallet: ```` ``` grin wallet send -d "http://108.196.200.233:13415" 20.0 2018-10-31T00:23:43.983935175-03:00 WARN grin - Using wallet configuration file at /home/arthur/.grin/grin-wallet.toml 2018-10-31T00:23:46.214033101-03:00 ERROR grin::cmd::wallet - Tx not created: Error { inner: Not enough funds. Required: 20005000000, Available: 0 } ``` ```` This last behaviour occurred in line 73,119,170 and 214 of the above pastebin. Have anyone ever experienced anything like this? ---

Hey Arthur, Thanks for letting us know. Could you post this message on Github (simply create an issue) so we can investigate this further? Thanks ---

Filed [https://github.com/mimblewimble/grin/issues/1909](https://github.com/mimblewimble/grin/issues/1909) just so we don’t lose this. ---

It happened to me, after cancelling a tx and some additional operations my balance was quite off. But in my case I was running a malfunctioning (for unrelated test purpose) version of grin so I decided it was my fault. I restored my balance with `grin wallet restore`. ---

@Arthur can you advise whether `grin wallet restore` fixes the issue? ---

I’m not 100% sure but I’m almost certain something similar happened to me. I was only mining and besides that don’t think I touched anything else. I checked my wallet balance (as I do a couple times a day) and it appeared lower from what I remembered the previous time checking it. I very briefly checked in some logs but didn’t find anything. Also, the timing for both of us lines up. This was recent. ---

@lehnberg I’ve renamed my current db directory as “db\_backup” and left the seed file untouched. After running `grin wallet restore` my total account balance was 0, compared to 1960 before. I don’t know if I did it right though. I could send my seed file or any needed file to facilitate the investigation. ---

I think I’ve managed to replicate the bug, I’ve posted some information in the github issue.
