Hostile time defaulting to 60 seconds

Hello Orange!
I tried this plugin, but unfortunately - even though it compiles and is loaded successfully - hostility timers are still the default 60 seconds if I attack anything/anyone. Please, let me know if I had to adjust permissions for this plugin too

If I understad correctly, this plugin does not need any permissions to set, does it?
I did everything accordingly to plugin documentation - my Oxide shows it as a loaded plugin, but if player attacks another player, the hostility timer is still the default 60 seconds, unfortunately.
I tried reloading oxide plugins and rebooting a server. Please, advice, as this is the only of the two plugins I'm using :)

Am I the only one who can't make it work? I searched whole web and can't find anything apparent that I've missed when setting it up. Please, help!
