Unless you're running 1.92 B 182/3 or running DOSBox, New Quest 2003 is officially dead in 2.53. The structural damage caught up and it just doesn't work, konks out in the first mini-dungeon.

Knew this day was coming. Sorry Gleeok and other purists.

The 2013 and Rebuilt are your options for this quest going forward in 2.53. Maybe if we get a special build or DOSBox working this will be functional again.

Sorry @Gleeok and @ZoriaRPG
