also I noticed even though I have the end overlap connected to "clear and invalidate timer by handle, it really doesn’t clear. it just stops where it is , and starts from there when I overlap again , instead of starting over. If I connect clear and invalidate timer by handle in the BeginOverlap side , no timer shows up, so it seems to work there.I mean generally , timer starts on BeginOverlap , if EndOverlap is connected to clear and invalidate timer by handle , it should clear it , wouldn’t it?
