hi...
in v 4 realms you can pillage during war 2 times in a week...so the question is...is there a way to know when an enemy can be pillaged again? without actually trying...and without keeping boring lists about it.... the flames do not help cause they last for 168 hours...and the white crosses in the map is of no use....
unfortunately no
you have to do it the painfully way : by checking through the espionnage menu and keeping track of who has been pillaged when ...
Have fun,
