WORLDEDIT-2849 - Reported by mmis1000

What I entered is "//g 2 random(xz)<0.5"
With 44*4 selected area.
And I got

下午 02:57:34 [SEVERE] com.sk89q.worldedit.expression.runtime.EvaluationException: Evaluation error: Exception caught while evaluating expression

in console

If it possible to prevent this or make a {color:gray}"random(seed)"{color} to provide seed-based random value?

a seed-based random value will be very helpful

Maybe it's no longer a bug.
