Any time I start casting a spell the addon starts throwing errors at a high rate. It worked well yesterday.

104x HeroLib\Class\Unit\Aura.lua:32: attempt to index local 'ThisSpell' (a nil value) [string "@HeroLib\Class\Unit\Aura.lua"]:32: in function <HeroLib\Class\Unit\Aura.lua:27> [string "=(tail call)"]: ? [string "@HeroLib\Class\Unit\Aura.lua"]:148: in function DebuffRemains'
