I must say it is disappointing to have to forgo a land expansion sale opportunity z(just popped up) as I had to already purchase 2 coal and now need to save 24 greenies (even with the 5 upgrade greenies I am currently at 14) to rebalance my city's electric grid after the v7 upgrade. It's going to be 4 weeks before I can purchase one Tesla assuming it's offered for sale, and another 8 weeks after to save up for a second and/or backup Tesla which translates to my game progress having been pushed back a minimum of 12 weeks due to the v7 update.
