The Achievement multipliers don't work correctly. When you attain more than one achievement at the same time. You don't get both multipliers you only get one. For instance when you have 3000 of everything else but newspapers when you hit that you don't get both the upgrade for hitting 3000 newspapers AND 3000 of everything. It says you got the achievement but profits don't go up accordingly.
Around level 285 the costs invert (except the lemonade stands). The newspapers become the most expensive to upgrade and the oil the least expensive. I suspect it is an issue with the multiplier at that level.
Yes! I don't know how to fight but I'm gonna launch a random attack on the enemy base and then after calling for a non-existent medic I'm gonna keep running towards the enemy til I'm surrounded and and killed!
