Orbs i believe are done by chaning a number in the sql stditems database. If you have the legendofmir.rar updates, there is a LOM2_Full file in there (/dbserver), i would suggest restoring your DB from there. Using that i havent had to change the table for orbs like i did using another.
I too am on td's files
For the txt files check they have the -0's etc in the file name. I get it alot when making new npcs and easy to fix.
