Nvm, i fixed it. For those who wants to change path of the lub files while diffing the client, make sure dont include .lub extensions on these 2 files
( OngoingQuestInfoList and RecommendedQuestInfoList ) as the default path also has no extensions in it.
Edit and change your npc script that using UNITTYPE to BL.
Example 1:
getmapxy(.@map$,.@x,.@y,UNITTYPE_NPC,strnpcinfo(0)); to getmapxy(.@map$,.@x,.@y,BL_NPC,strnpcinfo(0));
Example 2:
getmapxy(.@map$,.@x,.@y,UNITTYPE_PC,strnpcinfo(0)); to getmapxy(.@map$,.@x,.@y,BL_PC,strnpcinfo(0));
