Hey, I've been enjoying this game immensely after downloading it recently but have come into a fairly game breaking bug.
Welcome to C2C.
This post should be in the "Bugs and Crashes" thread. Also please read the first post of that thread, as it shows you the info you need to provide when reporting errors. i.e. what version are you playing.
I believe this bug was fixed along time ago, in the SVN version.
