Hey there !
I just discovered a nasty bug.
I have a homming missile that has a few "destroy" events. This one event runs even if the object does not exist. I have create at start unchecked and when I llook at the debugger it shows that there are none in the scene... yet that behavior event runs in a loop regardless :
target object count <= 0 create explosion object destroy missile
Now that object has "Create at start" unchecked and when I start the frame you can hear the explosions looping, basically that event runs in an infinite loop and tons of explosion objects are getting created. There are no missiles in the scene yet, I checked the debugger. :0
I still see my object counter in the debugger jittering. So I assume that this is not the only object getting created for no reasons and it's a paint in the trunk to debug. I only found out about that one event because it calls a sound every time it appears....
