Simulacrum and Steppe bugs

After patch 0.1.1.e:
- Bug found in Simulacrum: Kosis' ability which summons 2 spinning axes can sometimes will not disappear after the mob is dead and will continuously chase you, or sometimes they will stay at a certain place and will stil be spinning and dealing damage if you step in their AOE.
- Bug found in Steppe map: monster will automatically attack you when you enter the map (even if you don't move or press any button upon entering), resulting in an instant death. I tried to relog and re-enter the map, but still get attacked (normally the monsters will only attack if you move first). It's unfair and ruined my day.

Additional bug found:
- You cannot go out of the boss arena in certain maps (Steaming Spring for example) after killing the boss.
