After some time spend on redacting nav mesh my hl2dm map i understood that bots like to ignore nav mesh and move straight to the pickable item like healtkit, ammo, etc. and sometimes it even ignores if there is a wall infront of him or even when there is no item so the bots got stuck very frequently.

I suggest to add for bots ai function that will say them to follow nav mesh to get the item, so they won't go straight to it
