1st there is a topic where you can report your bugs there is no need to start a new one.
2nd this no bug you are blinded in the game this is a feature of this mod.
3rd what have you done to the mod this is a different font and also I can hear a music called "vista point" from the game (gothic 3) this is not part of this mod and I think you are using an old version of mount and blade this mod is for 1.011.
reach lvl 30 without speaking with the bloodfontaion (to be an antihero) and complete the museum quest (you will rewarded with eye of izanagi which cure blindness when used).
or use the evil eye to partially cure blindness.
there is no other way (at least in this version of S&S)
