I have started getting client crashes on the new .51 experimental servers. I was able to enter the game and play for around 10 minutes, but upon discovering my first zombie and killing it, the game crashed. After I tried to reenter the game 3 times, each time causing a crash right when I loaded in, I waited for five minutes, then tried again. This time, my character was about 100 meters behind where I had had the initial crashes and fought the first zombie. After running through the area that had started the crashed, and attracting a zombie (that looked the same as the one I had fought), I decided to run away from the area with the zombie behind me. After about 2 minutes of running, the amount of time it took for the zombie to fall out of view behind me, I crashed again. This was roughly 6 minutes after I had rejoined the server and not had a crash. After trying to rejoin, and getting the same type of immediate crash like I was getting after the first time I tried to log in, I decided to submit this error report. I believe I turned logs on after the first crash, so I think the log I'm going to attach has all the crashes but the first one.
