+## Uncomment to disable hard deleting garbage collection failures. (Hard deleting GC failures causes lag in order to bring memory usage down and keep bugged objects from hanging around and causing bugs in other things.) You can safely enable this for performance on production if the lag spikes are too disruptive)

+## Uncomment to disable hard deletes entirely, even things that explicitly request. This is not recommended unless you have a need for it during events or other high pop times where performance is key.
