An odd bug report on the AB40k site has popped up, and in looking into it further I've found I can get AB3.3 to load the roster correctly using the Load button on the game system dialog, but it won't load correctly using the File > Load roster option. Do these two load routines using different processing for handling the files? Is this an AB bug? Details including a roster file that is showing this glitch can be found here:
