Trait Trigger Structure Question

[Live2sculpt]

I am moving through educating myself on the function of various lines in triggers and traits. Catching on well in some cases. But one part that I haven't caught on is the loss of traits.

There are Levels to traits, there are Antitraits, and I've noticed Triggers to traits called Cleanup. But I'm not catching on yet.

How should I go about making a one-turn-only trait remove itself in the following turn?

And is it possible to give a character a trait within the same turn it is assigned anyway?

The objective being to affect a character with a special seasonal condition on a single turn. Would I have to structure the trigger to fire in the previous turn for it to take affect within the turn intended?

This is the current trigger structure.

Use WhenToTest CharacterTurnStart to fire your trigger and then use the cleanup trigger below to remove it.

Here's a simple cleanup trigger:

;------------------------------------------
Trigger cleanup_miserable
WhenToTest CharacterTurnEnd

Condition Trait Miserable = 1

Affects Miserable -1 Chance 100

Gotta go to a meeting and then the gym.
I hope someone can tell me where i went wrong when I get back to it tonight.

The message you got specifically means that the export list for the event CharacterTurnStart does not contain event_type which specified by the EventCounterType condition as being a requirement. Run it through my ATVTW validator and it will catch these types of errors.
