I haven't yet entirely completed playing through the mod, but I love it. It's a great concept, and generally pretty well done. Congrats...
There are a couple of things though that have been a bit painful. For some reason, every now and then I can't leave an interior to go back out into the city. Every attempt to exit by a particular door will result in a CTD. If I use recall, it works fine, and sometimes using a different door will work. In the same vein of events, sometimes if I save the game during a busy time in the mod (notably the city after completing what I consider the first main segment of the mod), trying to reload the savegame will result in a CTD, and there is no option other than loading a previous save.
Unfortunately, this cost me a character, as I had the quicksave and a full save that loaded me into the position of going directly to the same place where it again caused a CTD. I;m using MCP ver 1.9, so theoretically the quicksave should not have been corrupted, .and in any case that wouldn't have affected the other save. Any thoughts?
On a side note, I had the experience of being hit by a subway train... and found myself inside of the car. That was cool until the car reversed direction, and for some reason killed me... Not a complaint, I just found it interesting, eh?
