"Cannot read property 'suffle'" after restarting node

[Javi Rueda]

From tiem to time I stop my leader node and the Mongo server. After a few hours I restart them and I am consistently getting this TypeError which causes the start.sh to stop. When I try again, it just works.

Here I paste the log:

This bug is out I believe. Not sure what caused it back then but it's not happening anymore
