Panda said:Palisades are still in the build list when walls are available, even though they should be obsolete.
Rather a suggestion but a bug, but could you remove obsolete units from the build list as well? During the end game, it becomes a tad annoying to scroll through warriors and the like when macemen are available.
Units only obsolete if you can build all their upgrades, its a vanilla civ thing. The warriors stay because you cant build the drown.
