Error is: if actions simply not working on my pc:

Create(event) <
(Action) if there is an object at a position (an obj like info say)
start of block
change instance into (self -> obmove)
end of a block

(Action) if there is an object at a position (an obj like info say +not)
start of block
destroy the instance (self)
end of a block
>


(This code do = destroy both, the one over the collision and the one not hitting)
It suppose to change self if hit and if not destroy self. but when do work whit it it do delete all for some reason or non even that i told it to do only self if nothing are there.

I'm making a chess game to gain some skills in board game but this error keep not follow the role like it should. i even move all parts back whit collision point just to make sure but no luck. and coding list not helping to, plz make the same name as you make in actions els you take 30min to 2 hours just finding that one code you need i have done that before, and that killing once moral to make a game total, that list are way to big.

Forsomereason report did'nt go well to and i'm to tried to set me in to what they say so i report it here.
