Unchanged you'll run into it re-doing it on each loadup of a save, which may not be desirable once someone has started playing. Below I account for that, additionally added option to change the loadout or leave the default and just do the ready time change, and few tweaks for nil and error trapping, as well as allowing for any number of table entries without having to re-touch the rest of the code.
