ok, i'm on lvl 128. i raised the interest lvl to 70%, a few lvl. prior my score and gold got a minus sign in front of the number. score was 2 bill something, now every couple levels it subtracts my money and points. can't build towers when in the negative. every two or three levels it goes back to adding money and points. very strange. i tried the infinite money trick and it works, in both senario's negative and positive cash flow. not sure why this is happening. oh well, hoping to blow top score out of the water..........
