This exists primarily to improve things such as manual event execution as well as unify GUI actions into Conditions (see further below for how to enable "Wait" calls from your triggers).
How it works: by hooking the natives "TriggerAddAction" and "TriggerAddCondition + Condition", I can extract the function that is being passed to the natives and, subsequently, call that function manually instead of letting the trigger spit it out.
So with GUI triggers with conditions and actions, the conditions will be called manually and the actions will be called manually if the conditions are true.
If you don't want your Lua resource be affected by this, then I recommend using (Filter (or any other kind of boolexpr)) instead of (Condition) when defining conditions for your Lua trigger. I am not sure if anyone is using TriggerActions in Lua, nor why, but if you need multiple TriggerActions attached to the same trigger, then this resource will not work. A better solution for such odd scenarios is to switch your Actions to Conditions, or to use ExecuteFunc if you need waits.
Requires: [Lua] - Hook
To enable your trigger actions to use "Waits" again (ie. PolledWait), use [Lua] Perfect PolledWait (GUI-friendly) and put the following one line of Custom Script at the VERY TOP of your trigger actions list: if EnableWaits() then return end. The system will handle the rest.

-
Want to wait
-
Events
-
-------- Some event
-
-
Conditions
-
-------- Some conditions
-
-
Actions
-
Custom script: if EnableWaits() then return end
-
Wait - 0.50 seconds of game time
-
-------- Do further actions here.

Lua:
-- This is between 16-18 times slower than what is done with the Fast Triggers approach.
function ConditionalTriggerExecute(trig)
if IsTriggerEnabled(trig) and TriggerEvaluate(trig) then
