I believe there is another patch on the way "soon". I also am rather aggravated that TU seems to have made POA2 less stable. We used POA2 professionally for quite awhile, and it worked great, but with the 2.5 that came as part of TU, it is less stable, and each new patch seems to be improving (slightly) TU, but making POA2 more and more unstable.
Nevertheless, as you said... the theoretical possibilities are enough to keep me around. I do expect it will be a great work eventually... I just wish that he had waited to release it, until it was. Now, by the time it is fixed, it will have to draw back fans who long ago have given up on a rather expensive game that for several years now has failed to live up to the billing.
