I have patched my game to 1.02 is it worth patching to 1.03? will it make it that much difference?

Is it a bug with 1.02 that when u up grade a half-orc fighter to a crusader that her picture is changed to a dwarf? will 1.03 patch fix it if that the case?

Also when u use wizard eye is ther anywhere that lists ( a key code ) what the symbols mean? like yellow dots or up side down T? Only use it once so far when i was in Anskram Keep and trying to work outhow to get to what looked like starts by the bottom door ( turned out that i had been bugged ver 1.0 ,lol i had left the keep so the big demon did not appear. )

Well i done that and heading off to Drangheim for the second time so will reach the crusader bit again, so to patch or not to patch ?? .
