Productionizes #80615. The core optimization is this: ```patch - var/hint = to_delete.Destroy(arglist(args.Copy(2))) // Let our friend know they're about to get fucked up. + var/hint = to_delete.Destroy(force) // Let our friend know they're about to get fucked up. ``` We avoid a heap allocation in the form of copying the args over to a new list. A/B testing shows this results in 33% better overtime, and in a real round shaving off a full second of self time and 0.4 seconds of overtime--both of these would be doubled in the event this is merged as the new proc was only being run 50% of the time.
