A few people had reported crashes when using the packaged saved games, specifically for the Malk quest. With the help of one user, Alien FireFox, we were able to figure out it's only when using the saved games with the retail version of Vampire.
Hence, if you have the retail version of VTMB, the saved games packaged with the Clan Quest Mod will likely not work for you. I know this is unfortunate, and inconvenient, but please know that I'm working on generating a second set of saved games just for retail users.
Thanks everyone, for being patient. If you are a retail user (or any user for that matter) and experience any other issue, please let me know.
