Cloudspire
In a 4-player game, does a player whose fortress gate is destroyed keep taking turns?
The rulebook's 3- and 4-player section states this directly.

Yes. A defeated fortress gate does not affect your units, and you keep taking turns as normal. The player who landed the last hit pillages your Source (your Source drops to 0), you must repair the gate in the next Income Phase, and while it is defeated it cannot be anyone's mark.
