Let me describe a much, much simpler--and quite trivial UI glitch:
In the diplomacy -> build trade screen, you have toggles that let you adjust the amount of resources you propose to give. There is one for 10,000 and another for 100,000. When you "check" one of these and then "add" resources, it does them in multiples of 10,000 or 100,000 respectively. But when you "remove" resources, it just does them in increments of 1,000.
Yeah, yeah, this is so trivial, even I'm not going to mention it outside of here.
