I think these may be some bugs (1.01)
1. Was in city upgrade menu and had Guardian Statue as an option. Noticed that i didn't have enough crystal to build it so the build button was greyed out and could not select it. But when i double clicked on it in the menu it still put it in the build queue. It did deduct the 10 crystal needed and i was in the negative for crystal. (i was at like -8 crystal or something like that). Not totally sure if this is a bug.
2. In tactical combat when my unit is by an enemy unit and i want to reposition it to another tile by that same enemy unit (to better position myself for the next enemy after i kill that one) - sometimes my unit automatically attacks that enemy unit after it moves even though i dont click on the enemy.
