See error in console after a few runs of the command

Expected behaviour

Should not have the error in console

Actual behaviour

Has error in console. I carnt tell if the command runs for when the error appears

It looks like this would be fixed by moving this logic back onto the main server thread:

Essentials/Essentials/src/main/java/com/earth2me/essentials/commands/Commandbalancetop.java

Line 115 in 09dc49a

outputCache(sender, page);

Also, does this ever happen if you don't use a command block? For example, using a plugin to schedule the command execution instead. It seems unusual that this wouldn't already be an issue otherwise.

When runing the command myself no. i carnt test if running it from a plugin would cause it.
