Wait, this is a passive state? I totally missed that line in your original post...that's why I asked you back in post 12 if you were applying this state via a skill. I'm sorry for that, this whole thread was pointless.
Passive states don't have apply effects, because they are not applied/removed from an actor, only switched on and off.
You can go to my snippets post in my signature, I have a modification to the plugin to allow apply effects to work on passive states. I haven't tested it extensively, but you can give it a try.
The other alternative is if your actors have this state for the entire game, just make an autorun event on your first map that gives them the freezing counter variable. But then I'm curious about the remove state bit when TP is high enough, are you trying to do that to remove a passive state? That shouldn't work, either.
You should use that part to reset the freezing counter, and let the passive condition turn the state off.
