When go to do upgrade and it goes to resource page it isn't adding up the total when enter amount for resource. Example; need 40 more million wood for upgrade, enter 160 for 250,000 resource in the box for number to use and the total underneath stays at 0 instead of showing 40 million, but if you use the slide bar the total raises as you use it. Use to enter # needed and would give you total, now it doesn't.
