BOTS
}}
 * Fixed bots being too aggressive about destroying enemy items.
 * Fixed bug where bots would pick up items like Rapier or Aegis without giving humans a chance at them.
 * After all humans have picked heroes, the remaining bots will now immediately pick their heroes.
 * Fixed bug where bots would try to farm the same neutral camp that a human was farming.
 * Added support for bots buying and placing Observer Wards:
 * The more of a support a hero is, the more likely they are to buy wards.
 * If they have a human teammate, they will not purchase enough wards to fully deplete the store.
 * They will ward the runes, their jungle, and sometimes the enemy jungle (depending on how pushed the lanes are).
 * They won't go to locations to place wards if they think it's too dangerous.
 * Fixed bug that would sometimes prevent bots from defending their top/bottom lanes when the tier 3 towers/racks are gone.
 * Fixed bug where if the incoming threat was small, no one would ever be a selected to defend (typically resulting in no defensive response to creeps).
