Question The problem with slave collars

[SintSadze]

Please help, the opportunity to enslave has disappeared. There are collars in the inventory, and the slave owner perk is active. Previously, the R key "enslave" appeared in stealth mode, now this option is not available at all. So I can't finish the quest The Headless Gunman(((

Tell me, where can I find the numbers of the quest stages? Maybe the "SetStage" console will help.
