I think all of the HTC created maps have all the towns, etc. oriented the same way. Other creators have turned the town directions and base directions at times. Private message me your e-mail if you are interested and I will send you tables that tell you the direction theses objects are oriented at each base on those maps. There might be one or two of the newest maps that I don't have at this time, but I'll give you everything I have.
