Error when seeing barricade

[Pandaaa 2]

Hello,

 

Not just barricade also maps.

 

Here's my problem I have in my server a punching bag(damage tester npc) [cloned as barricade]

the first time i added it it works.. no errors nothing.. suddenly after some other edits when my Client screen come close to see barricade it gets error.

 

Help anyone

Why i am getting error on all pvp_n_ & pvp_y_ maps maybe there's more, what can i do?

i use a 2010-07-30 Client
