new spy tab is brilliant. im not sure its bug, but show old reports option works only if i have spies standing in provinces, not when are on route. also is possible to see only old reports by espionage tab for provinces where spies stand, not for all provinces with old reports
First part will be fixed today. I couldn't simulate the second one. Just a heads-up - last reports button shows last reports from the provinces of the player you currently spy on.
