I got my first bills and I started seasons on my game in late fall I turned on my thermostat to warmer costs more and my bill was $26,000!! haha (note to self set therm at cooler cost less!!)
Experiencing the same thing, yikes! I wonder if this needs a bit of retuning @SimGuruNick? I know the thermostat affects bills, which is great, but increasing them by thousands and thousands seems off! :o
