Fixed the first bug. If you want to fix it locally, change line 26 in PowerAuras\Types\Triggers\Loader.lua from:
Code:
tinsert(actionData["Stores"], class:InitialiseDataStore(params));
to
Code:
tinsert(actionData["Stores"], class:InitialiseDataStore(params) or false);
Having trouble reproducing the second, what abilities are you testing it with? (The one you're tracking via Spell Cooldown, and the ones you're using to invoke the GCD).
