Hovering a wand on a ArchitectureCraft block will crash the client with the following stacktrace:

If needed I can report this to ArchitectureCraft as well.

I've had this same issue--also on 10.2 (multiple times, just by accidentally selecting a wand, while my crosshair was on an ArchitectureCraft build). They do not play well together.

Have to uninstall BBW, else I cannot load the game in which the crash occurred (because the crosshairs are still hovering over the AC build, where it left off at the time of the crash).

@PsiPanther I just edit the world in mcedit and remove the arch. blocks im aiming at

@DeadSix27 Thanks for the idea. Unfortunately, it's easier for me to remove the mod (BBW), load the game, close the game, then add the mod back in. Because, in most cases (like this last crash), I'm working with elaborate AC builds (like large abstract art pieces, for example). So, not only do I not want to delete parts of those builds, I also am never sure which actual piece my cursor was on at the time of the crash.
