Body has no collision and doesn't receive damage

[correctmushroom2013]

Hey everyone! On my new map have a new droids (cortosis B2, BX droid etc.). They are don't have collision of the body (only). Their legs have a collision and get damage when I'm shoot on them. If I shoot at the body, the shells just fly through them without damage.
I tried create a new map only with this droids - all right. Mb this problem coz of my map has a lot of objects?

Here is errors what I got:
