I think I've found quite a severe bug : If you meet enemies in the BF who are trapped in a "black area", you know, the area filled with black colour where normally no-one can go into , and you use the Shaman's Hammer, then you'll get an instant Black Screen !
Everything is black, except minimap, and user interface.
You'll get your view back via reloading, but using the hammer again, even in normal (non-black) areas, the same thing happens again !
I think this needs to be fixed !
I use 1.45, English version.
