Changelog

• Tithe Barns was intended to provide 30 stone every minute. Originally, Tithe Barns provided only 15 stone every minute. With the Season One Update, it was fixed.
• Mongols: With the Season One update, a bug was fixed where Tithe Barns research time was 80 seconds instead of the intended 60 seconds. It also gives the proper +30 food, wood, and stone instead of +20. With the Season Two Update, the Improved version also provides the correct amount of resources.
• Originally, the base research time for the Delhi Sultanate was 5x default (300 seconds). With update 8324, this was increased to 15x default (900 seconds). With Season Two Update 17718, it takes 12x as long (720 seconds).
• Holy Roman Empire: With update 24916, fixed an issue with the Tithe Barns technology where it was providing only 20 stone every minute, instead of the intended 30.
• With patch 9.2.628, Tithe Barns was removed from the Japanese.
• Originally, Tithe Barns provided an extra 30 food, 30 wood, 30 stone and Improved Tithe Barns provided 45 food, 45 wood, 45 stone. With patch 9.2.628, these amounts were changed to 40 food, 40 wood, 10 stone and 60 food, 60 wood, 15 stone respectively

Campaign version

Because the original four campaigns have not been rebalanced since the release of the game, Tithe Barns costs 650 gold in those campaigns. It otherwise has the same effect. The Mongols also do not have access to this technology in the The Mongol Empire campaign.
