Yeah, for THM/BLM make sure your Rest Energy is set to 0.
Also check your "Use Fire Until" setting (at least that's what it's called in the version I remade) and make sure it's set properly as Magitek has this code in it to use Transpose if you're under lvl 38:
Code:
// If we're below 38 it means we don't have Blizzard III, we need to Transpose when we get below our setting.
new Decorator(r => Core.Player.ClassLevel < 38, new PrioritySelector(
Casting.Cast(r => "Transpose", r => HasAnyAstral && Core.Player.CurrentManaPercent < WindowSettings.BlackMageBlizzardIIIMana, r => Core.Player, r => 2, r => false))));
(it says Blizzard III Mana but in English it means "Use fire until this mana %" which is why I renamed it in the settings menu)
Basically, treat "Use Fire Until" as your Rest Energy setting as THM. Let us know if changing these things works for you.
