A possible thread conflict.

In a scene with a various collision nodes, each node is a instance that call a function in Player node.
My Player collides with two nodes at same time and cause a crashes in the game window and close it, a debugger instance is lose too.

Its issue not occurs in all time, but the little incidence (almost 10%) is worrying.

I hope these info can help.

scene

Node Healt

extends Area2D

var taken=false

var player = null
var playerDT = null

var tipo = "healt"
var value = 20

func _on_body_enter( body ):
    if (not taken ): #and body extends player):
        taken=true
        playerDT.incHealt(value)
        get_parent().remove_child(self)

func _ready():
    player = get_node("/root/stage/Player")
    playerDT = get_node("/root/playerdata")

Well, some a lot of crashes and tests to I see that it does when a two or more collisions trigger events when I manipulate a scene tree.
When a node is removed, physical server sometimes call a destroyed object, or vice versa.

This appears to solve in GDScript level

func _on_body_enter( body):
    #some code ...
    set_block_signals(true)
    set_contect_monitor(false)
    set_active(false)
    queue_free()
    get_parent().remove_child(self)

And my game running for minutes without crash ^^

oh, you don't really need to call remove_child(self). when deleted by
queue_free(), the node will be removed too

Sounds fine to me. Very thanks.
But, apparently queue_free was forgotten in documentation, both in Wiki like in IDE Help.
