Prevent a crowd agent from dying.

I have a few zombie crowd agents and a dynamic game crowd destination attached to my player so that they can chace me.

Lets say im in a 90º corridor.The moment i turn at the corner those guys will try to follow me but in a bad attempt ,they just hit againts the wall and brute force walk against the wall untill they make it to the corner and from there is easy.(im working on it).

The thing is that the ones that dont make it to the corner die.If they go too much againts a wall in a attemt to make the 90º turn and dont make it,the engine just delete them.

Ive been looking at the MobileGameCrowdAgent and the utGameCrowdAgent but i dont see anything that can prevent them from dissapearing when such a ¨¨obstacle¨¨ is reached.
