I'm getting that Red Eclipse bug without ever having left Nar Shaddaa. In fact the cutscene triggered a second time as I was on my way to the Ebon Hawk after it played the 1st time. After I finished the quest it triggered a 3rd time.
Any chance you can upload the fix to K-Files or somewhere else? You site gives an error about exceeding the download limit (which must either be a bug in the script or you are basing it on broad IP ranges).
Additionally, I've encountered a number of (seemingly random) game freezes on Nar Shaddaa. It was smooth sailing on Peragus and Telos - no bugs or lockups/freezes encountered. There is nothing much else installed in the way of mods bar a few cosmetic things and High Level Force Powers.
