Hero Removal, Creep Spawn & Leaks

[Craphter]

Ok so I have 3 problems:
1- After a player buys a hero from a tavern, I want it to disappear, I really don't know how to.
2- I'm having serious problems with creep spawns, there's only one trigger:

• First Wave
  • Events
    • Time - Elapsed game time is 5.00 seconds
  • Conditions
  • Actions
    • Custom script: set bj_wantDestroyGroup = true
    • Unit - Create 3 Guerrero for Neutral Hostile at (Center of Creep Spawn R <gen>) facing (Position of Fountain of Health 0000 <gen>)
    • Unit - Create 2 Arquera for Neutral Hostile at (Center of Creep Spawn R <gen>) facing (Position of Fountain of Health 0000 <gen>)
    • Unit - Create 2 Arquera for Neutral Hostile at (Center of Creep Spawn T <gen>) facing (Position of Fountain of Health 0000 <gen>)
    • Unit - Create 3 Guerrero for Neutral Hostile at (Center of Creep Spawn T <gen>) facing (Position of Fountain of Health 0000 <gen>)
    • Unit - Create 3 Guerrero for Neutral Hostile at (Center of Creep Spawn L <gen>) facing (Position of Fountain of Health 0000 <gen>)
    • Unit - Create 2 Arquera for Neutral Hostile at (Center of Creep Spawn L <gen>) facing (Position of Fountain of Health 0000 <gen>)
    • Unit Group - Pick every unit in (Units in Creep Spawn R <gen>) and do (Actions)
      • Loop - Actions
        • Unit - Order (Picked unit) to Attack Fountain of Health 0000 <gen>
    • Unit Group - Pick every unit in (Units in Creep Spawn T <gen>) and do (Actions)
      • Loop - Actions
        • Unit - Order (Picked unit) to Attack Fountain of Health 0000 <gen>
    • Unit Group - Pick every unit in (Units in Creep Spawn L <gen>) and do (Actions)
      • Loop - Actions
        • Unit - Order (Picked unit) to Attack Fountain of Health 0000 <gen>

But after X seconds, THEY ALL GO BACK, they don't even reach the fountain, I do not know why they do this

And third, I would like to ask somebody to check if my map is leak-proof, they're just a few triggers, so it wouldn't take much more than 30 secs.

Thanks!

Gameplay constants... Edit the field for creep gaurd distance and time and make them a stupidly large value. When units hit these values, they return to their place of origan (where they spawned).
