Item duplication bug

I've only touch on .ai files and only do a checking related to items which is whether a hero carries a town portal scroll. Something is causing this bug to happen when the map is played with more than 2 computer player in LAN.

noone can debug code by screenshot.

go to "magic related" forums...

I just have to remark.. but i've never seen so many items on screen at once in my life o_O

forget about the code. i've used alternatives. it was cause by copy group functions. once i replace it with another way to dupe group then the prob no longer exist.

i've a function which check enemy units which are near my town and if there is it will set some boolean to true. but then it just dupe those item in location 0,0 for no reason.
