Made new level and my AI won't chase me!

HI guys
have two levels that works fine with AI chasing me… now i made new level with streaming level … and
for some reason my character won’t chase me anymore …
tried creating nav mesh … and still no reaction!

can anyone explain me why in this level i cant manage to get chased !?

i managed to make it work… by setting the persistent level as current level .
still looks like it’s wrong way… but at least it works!

You have to store Nav Mesh on persistent level.
