Items ignored in Price List will be skipped over quickly during list items from inventory/retainer.
Outgoing packets (casting movement hack) determined to be fragments will be skipped. If this is affecting the functionality of the hack for you, I would check your MTU size, and be sure to check the MTU of any VPN you are using. In general, outgoing packets are very small and should not be fragmented.
This requires updating Speeder to the newest version.
