Problem: Before, agents positions were tracked frame-wise. So collision could just check for that point position. Now, after introducing fixed update, we have agents path points distributed by much larger distance, so just simple point collision test wont find all collisions. We need to detect collisions in between updates because during that time, we have no control over agents velocity.
