Akka.Cluster.Sharding.RepairTool
In addition to the work done on Akka.NET itself, we've also created a separate tool for cleaning up any left-over data in the event of an Akka.Cluster.Sharding cluster running with akka.cluster.sharding.state-store-mode=persistence was terminated abruptly before it had a chance to cleanup.

We've added documentation to the Akka.NET website that explains how to use this tool here: https://getakka.net/articles/clustering/cluster-sharding.html#cleaning-up-akkapersistence-shard-state

And the tool itself has documentation here: https://github.com/petabridge/Akka.Cluster.Sharding.RepairTool
