Three scripts used in the "Routine Delivery" quest, TR_m3_RDDorogGroDurin-Script, TR_m3_RDHlesVervul-Script, and TR_m3_RDSuladaSyrivis-Script have all misspelled the name of the local variable "T_Local_Khajiit" as "T_Local_Khajit" in the declaration. In my experience, this is likely to cause an expression error on the original engine, making the scripts unfunctional. Given that none of the affected NPCs are Khajiit, the best solution would be to cut the Khajiit identification sections entirely.
