In your Set Timer by Function Name node, there is a time float that sets how often to run the function. That is what I meant by setting that value to 0.05 or less, but it actually should just be set to every couple of frames.
But I actually tried testing this out on the default Inventory Player Controller and the default map that comes with the pack. It didn’t seem to make a difference at all, so I would just ignore the timer function and keep it on the tick. The main reason you would want to take it off the tick function is that if you actually want to be able to stop and start the hit scans to save some client actions.
