2 were attacking my 6 in the province above the enemy's capital. I sent 4 to that battle and went to sleep. When I awoke I had 9 there and the enemy was gone. When I click the province and morale, it shows I have 9 garrison strength. When I click the 9 troops, it shows they have 0 strength. It shows the 9 are in combat with no casualties. I have the option to attack and the option to split. The other options including move are gone. Their morale is 69 percent. When I click split, it makes the 9 disappear from the map and I don't get the popup to split them.
I sent 3 more. I moved past the city with the 9. I moved them back into the city with the 9. Now I have the above with 12, not 9.
The above happened right when I could have moved most of my nine against the enemy capital. What did that player do to me and how long will it last? Alternatively, if the game shows my units are in battle and I cannot move or split them, when I see no enemy units in my province, how to I get the battle to turn off? Thank you.
