Yesterday I had issues with attacks, as during battles with cities with level 1 fortress it would not show me enemy strength. Then, during the night, 1 battle crusier has basically dissapeared. No battle report. The enemy does not have any navy units, nor artillery. But the cruiser is not where I left it. Now this morning I am launching an attack into a a city that suddenly shows defender strength. Claim 9 units. After the firsts attacks with 37 units, the information shows 2 kills, but the city stats still show 9 units garrisoned. Another city to the north, also showing 9 units garrisoned, has sent reinforcements, 3 units, but still shows 9 units garrisoned.
Any explanation of what is going on?.
