nobranch mapflag Not Working

[Vyserion]

Hello guys,

  I'm using a rAthena version from 6 months ago, downloaded from official github (can't determine version), however, when I use a dead branch on a map with "nobranch mapflag" the monsters are actually spawned but the item is not consumed. 

I keep on using it but does not consume it.

EDIT: I tried to duplicate the item with another Item ID and it worked, however, is not being considered for the "nobranch" mapflag, so I think something is wrong with the mapflag itself being linked to item 604. Any idea how to fix it? or where to look at?

This is the item_db script:

604,Branch_Of_Dead_Tree,Dead Branch,2,50,,50,,,,,0xFFFFFFFF,7,2,,,,,,{ monster "this",-1,-1,"--ja--",-1,1,""; },{},{}

Does anyone have any clue on how to fix it?
