Several times, yes.

I've been keeping edit mode on OpenIV active while putting the mods where I'm pretty sure they belong (GTAV\mods\update\x64\dlcpacks\addonpeds\dlc.rpf\peds.rpf) and I type the name of the mod in addonpeds editor properly, but I'm sure I'm doing something wrong. I dunno what it is.

The peds menu shows up in-game (though my keyboard commands seem to have been getting screwy after finally installing it), and it'll show the peds as I typed them in the editor, but when I try to select one, it just says the mod isn't in the folder. Do I need to do something different with the editor? Or do something in the dlclist.xml file (other than the <Item>dlcpacks:\addonpeds</Item> line)?
