[Solved] Double spawned objects. Solution?

I have an event where

Object A:On collision with object B, set all objects on layout destroyed.

I have about 5 different objects on the layout and I put them in a family, where I can destroy them on collision.

When I restart the layout after that, Object A is spawned twice immediately, instead of just one.

Is there a solution to this? I thought I already destroyed all objects before the layout restarts.

Do you have one instance of the object sitting on the layout to begin with before spawning the others?

If so make sure you do a

on start of layout - object destroy

to clear all instances first.

its probably just one of your original instances still on the layout

I sort of came up with a workaround. Basically assign a global variable to them and disable events following collision. That solved the issue in my case. Probably not the best way but it worked somehow.
