# Postmortem for incomplete LEAP validator reward claim for 29 June till 28 Sept period
On Sept 28 @kosta claimed a period rewards from a single Leap Mainnet validator for block interval 8047181 — 8637840 (roughly June 29th — Sept 28th)[[1]](https://leapdao.slack.com/archives/C75C00YJD/p1569682999002100).
As result 785002 LEAP tokens were claimed and distributed proportionally to team reputation [[2]](https://leapdao.slack.com/archives/C75C00YJD/p1569859711003000).
## Problem
However, on Aug 18th there was a planned upgrade of mainnet Operator contract which changed signature for Submission event (it is used to claim rewards). Because of that no events were actually read for Aug 18th — Sept 28th period.
## Resolution
- update claim script with new Operator ABI.
- claim rewards for 8373756—8637840 block interval (Aug 18th — Sept 28th)
- distribute using the same proportion [[2]](https://leapdao.slack.com/archives/C75C00YJD/p1569859711003000)
As the result, we will have all the rewards for June 29th — Sept 28th distributed according to reputation in the same period. Like it was intended.
