My Dupe gets undone/disappear randomely

[Suppressor]

I made this little tank and it gets undone it self randomly, I use Advanced Duplicator 2 on a ACF build server and I've tried spawning that on other servers too, When I spawn it right away and its frozen in the mid air, it doesn't undo it self and when I unfreeze it and don't use it, but when I get in the seat and start rolling around it randomly gets undone, Oh and whenever advanced duplicator finishes duping/pasting it, it says
Warning: Unhandled usermessage 'Undone'

Well, my tank's info
Two E2 chips that works fine on other vehicles
90 Props
Correct Parenting
Prop coloring and changing material
3 ACF Ammo box
2 ACF Fuel tanks
1 ACF 50mm Cannon
2 V6 Engines

I really don't get this..

Sorry for my bad English and please help :( :(
