When you Continuous Attack and lose a certain number of troops the little Blip window thingy (whatever it's called) that pops up next your original territory will only display a "-" sign if the number is too big (it will show some double digits, but seems like 15ish or so it starts not displaying). So just a font size thing it seems. This may only be when you actually succeed in taking the country as well (are there different box sizes if you lose and if you win?).
Similarly, I wouldn't mind see the Dice Roll/Loss information stay in the Header Bar (next to Place/Attack/Fortify/etc) a bit longer or until your next Attack/Fortify.
Just small display issues.
I'm still seeing the "-" at times in both (I believe both) the defending and attacking boxes at times.
Even after:
