I`m currently trying out your mod, it`s really fun, I like it that units don`t die from one attack, but are a bit more powerful...
but! I`ve, already twice, had the same problem. Since 2 units can now stack on one hex, it usually turns out that some other civ, that i`m not at war with stacks one of his units over my current enemy. As i click to attack, even if it shows in the lower window that i`ll be attacking the enemy unit not the friendly one, a window pops up asking wether i want to declare war on this civ or not, and there`s no way getting rid of it. neither of the options work, nor does Close.
I think it should be only right if you could stack only your units, the AI respectively only their.
Looking forward to hearing from you.
Your mod definatly deserves 9/10 already.
