I was deciding to expand my arena by 1000 Bleachers and 100 Lower Tier. It will cost me $270 000 but when i click confirm there was a connection error, so i refresh the page and the expansion was successful and will take 10 days. However when i go to my economy page it shows that $540 000 was deducted instead!!! It was twice the amt and how can i reflect this to bb?
