Hirion engine + Gathering Nodes problem

[Kira]

Hey guys!

While being pretty sure this is a simple fix, I'm not good enough at scripting to do this myself.

So the problem is this:

Activating a gathering node in the world as you start to "gather" it, pressing the open menu button any time during that

gather event the game crashes

saying:

"script 'main menu' line 533:NoMethodError occured.    
undefined method 'current_symbol' for nil:NILClass"

line 533 sais for me :  if @last_symbol != @command_window.current_symbol

I think the error origins from : Hirion Engine - Main Menu  Author: Nicke http://forums.rpgmakerweb.com/index.php?/topic/19644-he-main-menu/

this is other script im using for gathering nodes : http://daimonioustails.weebly.com/gathering-nodes.html

In my mind I'm thinking simply adding a snippet of code so the menu acces is disabled during the gathering process would fix this

IF I only knew how to code

Thinking of starting to learn ruby soon XD

please halp!

tank you in advance!
