Zombie Event Problem 0.3.6

[Teddy]

Hello guys i use this script "http://otland.net/f82/zombie-event-new-version-bug-free-updated-128664/"
All works fine but i got one problem..
When someone use magic wall in arena (no-logout zone and no pvp zone)
This item come:

21:26 You see an item of type 11095, please report it to gamemaster.
ItemID: [11095].

Magic wall rune works fine outside the arena?.. but how do i fix this so it wont work in no pvp zone or in this arena!?


Magic wall rune script

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_ENERGY)
setCombatParam(combat, COMBAT_PARAM_CREATEITEM, 1498)

function onCastSpell(cid, var)
return doCombat(cid, combat, var)
end
