Bug description

/baltop has usually worked fine on our server, but at some point recently it stopped working and now prints a NullPointerException in the console.

We did recently update from EssentialsX v2.19.7 to v2.20.0, so that could be a factor here, but I can't be 100% certain that the problem started happening after we updated.

Steps to reproduce

1. Run /baltop

Expected behaviour

/baltop should state something like "Ordering balances of 10,315 users, please wait...", and then a few moments later the players with the largest balances on the server should be shown.

Actual behaviour

The "Ordering balances of 10,315 users, please wait..." message does appear, but no players or balances are shown. Instead the NullPointerException appears in the console.
