Lost Viewindex after failed rebalance

Hi

I had today a strange issue. We have a 5 node 4.0 CE cluster running and after some maintenance on node 5 I started the rebalance to add the node back in.
Unfortunately the rebalance failed and now is one of our views empty. The cluster automatically started to reindex the view but this is an expected behavior and never happend before.

Does anybody of you now how to avoid such behavior?

Thanks for your help
