In v0.19.0.1, I’m running regtest, creating a wallet with avoid_reuse=true, generating 31 blocks in that wallet, then generating 100 more blocks to a throwaway address to have the rewards mature.
Then I send 1 BTC to a throwaway address, expecting to see all 31 block rewards spent at once, but the resulting transaction only has 1 input. The other 30 rewards show as "reused":true when I listunspent, but when I run getbalances I see them showing us as trusted, not as used like I would expect.
Here’s a log:
