The revenge button should be disabled if we can't attack their base. I get really sick of hitting all revenges just to see which person I can revenge in my list. It'd be really useful if I knew who i could revenge so I would know which bases to check out. Also really annoying if you hit "yes confirm I want to break my shield", but then you can't revenge the guy so the next time you hit revenge the same message pops up.
Thanks!
