I’m experiencing what appears to be a mismatch between the on-chain NIGHT redemption state and the state maintained by the redemption backend.

My first NIGHT thaw was successfully redeemed on-chain. The tokens were received in the registered destination wallet and I was later able to transfer them normally.

However, the Midnight Redemption Portal currently shows:

**Redeemed so far: 0 NIGHT**

The `/schedule` endpoint also appears not to recognize the successful first redemption. It reports zero claimed allocations, the earlier thaw as skipped, and no transaction ID for the previous redemption.

As a result, the currently displayed redeemable amount appears to include the NIGHT that was already successfully redeemed on-chain.

When I try to redeem the currently available thaw(s), the transaction cannot be built. The request to:

`POST /thaws/{destination_address}/transactions/build`

consistently returns:

**HTTP 500 Internal Server Error**

with:

`{"body":null,"message":"Internal Server Error"}`

This does not appear to be caused by insufficient ADA. I originally experienced the same problem using Yoroi. There’re more than 20 ADA available. The problem persists with another wallet interface and sufficient available ADA.

The on-chain transaction history clearly shows that the first thaw was successfully redeemed, while the current Redemption Portal/backend reports that nothing has been redeemed.

**Has anyone else experienced this specific state mismatch?**

More importantly, could someone from the Midnight team confirm whether the redemption backend can be reconciled with the successful on-chain redemption?

I have already contacted support twice but have not yet received a response.
