When sending I has this error
16 bad-tnx-orchard-unknown-anchor
It happened on iOS as I detail in this issue [iOS] unable to send. error 16 bad-tnx-orchard-unknown-anchor · Issue #95 · hhanh00/zwallet · GitHub
But this seems to be a transaction builder problem, are other users having this issue in other platforms?
Thanks for the bug report. I need to investigate the root cause. For the moment, you could try rewinding to a previous checkpoint (under the advanced menu).
Sure! I didn’t want to do it without reporting the issue and getting some feedback from you first just in case there was some debug stuff that would be lost
I confirm that rescanning fixes the issue, but this should be looked into.
probably the wallet didn’t account for a reorg or a note spent with another wallet. I have this same keys in many wallets since it’s a test wallet (on mainnet, kids don’t try this at home 
)
I replied the above test over github as well
You are more than welcome to look into the matter :). As a matter of fact, that would be a real test for a job of a wallet community developer 
The regtest datasets of darksidewalletd would be the perfect thing to exercise that! 
Agreed but no one has volunteered or is funded to do this work. Afaik, there is no standard regression test suite for zcash wallets.
Agree!
Even though we share the same synthetic blockchain dataset every sync algorithm will have its nuances and expectations to meet.
I’ll reply there
