When disabled the normal Mail Carrier situation will run, if this setting is changed after KW is started you will need to save/load. There is a new Loverslab menu in Kinky World -> Settings, I also made some other changes, most of them can be toggled on/off if you don't like them. I made some changes to get rid of the lag the mod seems to be generating on modern CPUs, I have eliminated most of the lag generated by KW but there are still the occasional 'hiccups' now and then that I haven't been able to isolate yet.
