From the rules reference, under play action (p. 16), it says:
- A card with the fast keyword[...] may be played any time its specified triggering condition is met or, if it has no triggering condition, during an appropriate player window (see “Fast” on page 11).
Under fast actions (p. 11), it says:
- A fast event card may be played from a player’s hand any time its play instructions specify. [...]
- A fast asset may be played by an investigator during any player window on his or her turn
Now, almost all fast events have a timing instruction, but Hiding Spot does not.
So I guess my question is: What is an appropriate player window for Hiding Spot? Can I play it only during my turn (same as fast assets), or can I play it during any player window during a round?
