52 Q-Coherence Chip

Q-Coherence Chip is trashed whenever a program is trashed, even if the program was not installed

The place I first saw the ruling, on bgg:

The recently spoiled card Q-Coherence Chip reads "Trash Q-Coherence Chip when a program is trashed." Does that apply to programs trashed from the Runner's grip (due to damage and/or discarding) or only to programs trashed from in play?

Thanks for the question. Yes, that does apply to programs that are trashed while they are not installed. Hope that helps,

Per the rulebook (in a call-out box in the Corporation's turn description on page 14).

A discarded card is not considered to have been trashed, and vice versa. Cards that prevent a card from being trashed cannot prevent a card from being discarded

 

So, just discarding programs doesn't trigger Q-Coherence's flaw, but programs trashed from the grip by damage does trigger it.

An interesting development...from the ffg site https://www.fantasyf...rade-your-game/

 

Welcome to FAQ 2.0! First of all, don’t worry about the new version number; we are just updating it to mark the new year and some minor changes.

The new FAQ answers questions about cards through the Order and Chaos Expansion and clarifies the timing of nested triggers. It also introduces two errata to the game. Both errata add the word “installed” to a card in an effort to simplify its use during the course of a game. Before, the Runner could choose to trash a program from his or her grip as the result of the Burke Bugs subroutine, which was not the intent of the card. In addition, Q-coherence Chip had a similar interaction that was not intuitive; whenever a program was trashed, even when not installed, the Chip was also trashed. Now, both of these cards only affect installed cards.

That changes everything.
