Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?

%%%Apparently there are some bizarre interactions going on between a property sensor set to interval mode, a property actuator set to copy mode, having the Debug Properties option enabled, and having debug information enabled on the property you're copying to. Note that the property actuator must be set to copy mode, and the property sensor mush be in interval mode. Changing either causes the bug to disappear.
My best guess as to why this is happening is that the debugging info system is creating a new tracker for the property you are copying to each time the copy property actuator gets activated (though I have no idea how the property interval sensor comes into this). It'll take some digging in the source code to figure out exactly what causes the issue.
I've attached the simplest blend I could create with the issue. Notice that Blender's memory usage steadily increases while the game engine is running.%%%
Changed status to: 'Open'
%%%I also noticed that the same issue occurs when there is an additional property sensor set to any mode beside interval. weird_memory2.blend demonstrates this.%%%
