addChild fails randomly

[Axonn]

Hi everybody. I'm coding a game and have run into a weird issue. addChild fails. RANDOMLY.

I keep creating enemies and objects in a rather fast loop, calling addChild(object). Each time I call addChild I increase a variable X.

After 5 minutes:

stage.numChildren = 50
X = 60

I must also specify that I am sometimes adding objects at a rate of 5/second. I'm also removing them, of course, otherwise the FlashPlayer would freeze. When I am removing objects, I, of course, decrease X. Still, things get out of sync and I cannot understand why this happens. Also worth mentioning is that I never have more than 200 objects on the stage. I always remove them and add them in a single place so I got everything very "centralized" so to speak.

What's even weirder is that apparently AS skips some instructions when it's too loaded. I have a request for an animation to go and play at a certain frame, and it doesn't. I'm very puzzled by this behavior.

How does it fail? What is the error? Not enough specifics

I narrowed down the problem a bit. I have 2 functions which add and remove ALL OBJECTS from / to the stage. All stage work is done there:

addObject (movie)
removeObject (movie)

I monitor function calls on those. And here is the interesting result:
start with stage.numChildren = 0
addObject = 1200 calls.
removeObject = 1000 calls.
end with stage.numChildren = 6 (!?!?!?!?!?!)

Now... how is it possible for 1200 calls to addObject and only 1000 removals, to result in only 6 kids on the stage !? I don't get it!!!

I have no errors whatsoever when running this, I have not supressed any error with try/catch and I always provide valid movie clips to addObject and I actually SEE THEM appear on the stage.

Is it possible that an object is removed by Flash BEFORE I REMOVE IT?
