The freeze doesn't happen before chapters 3 or 4, so it seems to be something specific to that part. I haven't beaten the game yet, so there's still chance it'll freeze again at some other point, but so far the translation is top notch quality, outside that one problem.
I sent Tom a private message on RHDN forums, but he hasn't been active here for like two weeks, so I don't know how long it'll take him to read it. Maybe someone here can contact him outside these forums and let him know about the bug more quickly. Also, I don't know if him or DDS will keep supporting the patch, but I still thought it'd be good to let people know.
