Strange problem on quest

i added quests on NPC i have made and done successfully added

but the problem that players can see and another can't see even if i restarted server new character
btw im instant Lv.110 so some players can't see the quests on whole server btw normal quests too and some players is normaly
btw i was see the quests and i have quest of the list and when i back to town to complete it i can't see any quest

so any suggest or idea what's going on ?

# 1-Edit:
i tried now to create new Account with new character and when i check the NPC i see the quests

# 2-Edit:
the strange that some time i see the quests on npc and sometime no , also not only my new quests disappeared no all quests on game disappeared :( much strange right !

# 3-Edit: When this strange bug happen ( all game quest disappeared to player ) when kill unique / mob etc nothing ( No exp,gold,sp,item ,etc )

maybe there are some conditions in the lua scripts so only specific players can actually see the quests i know that there is JOB STATE limitation like Hunter/Thief or race limits like CH/EU and level limit so check ur lua scripts :)

up ???????
