Yanfly's Skill Core and Skill Cooldowns don't seem to work (solved)

Hey ;)

I'm trying to use Yanfly's skill core ( http://yanfly.moe/2015/10/13/yep-8-skill-core/ ) to make a skill costs a percentage of the hp of the user. (like this : <HP Cost: 15%>)
In combat menu, it does work, hp cost is showed, but when the actor lauches the skill, he doesn't loose any hp (but the skill still lauches).
Same thing with Yanfly Skill Cooldowns, when writing <Cooldown: 7> in the note tag, skill lauches properly but no cooldows is applied.
My plugin order is well, ordered (strictly follows Yanfly recommendation), and when I use the F8 console after lauching a bugged skill, no bug appears (game doesn't crash).
Game and project are 1.6.1 and even when I try to use Skill Core and Skill Cooldowns on another new project, it still doesn't work (but doesn't crash either).

Do you guys have an idea of what is making these plugins bug ?
(and sorry, English isn't my first language so I hope I was clear in my explanation)

What other plugins do you have? Tried turning all non yanfly plugins off?

Show us a screenshot of your plugin manager with all plugins listed

Alright, Nevermind, finally found what was broken here : Valhalla Engine Plugins System : Bloodmage was in conflict with Skill Core I believe. Thanks, didn't think of turning off every non Yanfly's plugins <3

That's solved so :)
