1.47 really fixed a lot of little noticable bugs... and the ones that are not fixed are OMO not too serious.... some facial paint.... (not that most people would notice it)... a few small changes to specific objects' behaviour (there are 2 places i know of where you can lockpick, shoot, loot through a wall, get shot through the wall, shoot through the wall, but not WALK through the wall)
Small things....
