Help [Warning]: Invalid menu selection

[Petey Pablo]

How do I find this warning? Anyone can help me with this? Thank you!

[Warning]: Invalid menu selection on npc 110286862:'invalid npc id' - got 8, valid range is [1..0] (player AID:2000032, CID:150071, name:'WoooT')!

i don't think it is a npc problem, could be the player was lagging and sent out a menu request after the window was closed or the npc was unloaded
