How can I Recover from Snapshot Exception?

Elastic Stack Elasticsearch

I take a snapshot of a cluster every night using Curator to snapshot the last 7 days of indices. I am doing this in preparation for an upgrade from ES2.3 to ES5.2 which is scheduled for this evening so wanted to have a back up in case it goes wrong. This morning I check the snapshot and get the following error when trying to list the snapshots:

{
   "error": {
  "root_cause": [
     {
        "type": "snapshot_exception",
        "reason": "[sip_cdr:sip-cdr-20170223031001] Snapshot could not be read"
     }
  ],
  "type": "snapshot_exception",
  "reason": "[sip_cdr:sip-cdr-20170223031001] Snapshot could not be read",
  "caused_by": {
     "type": "illegal_state_exception",
     "reason": "class org.apache.lucene.store.BufferedChecksumIndexInput cannot seek backwards (pos=-16 getFilePointer()=0)"
  }
   },
   "status": 500
}

It looks like there was an issue with the last snapshot attempt this morning. How can I recover from this without trashing the 'good' snapshots in my repository?

Sorry, I panicked. Turns put I can just delete the effected snapshot.
