Pocus, maybe the green dragon was in dragon form or you gave him a shape shift command. If not then this bug is limited to the dragon, as I have noticed pretenders that it certainly does not affect.
Edit: Well, HJ beat me to it. Also, under the unit screen by rightclicking, shift D and shift C bring up interesting looking screens that don't quite look intentionally left there. Try it yourself and see.
Although shift C can be useful actually.
