for example, if the seller disappears in the player's house, then all its contents are transferred to the house sign, and all items will have a parametert of map = Internal.
But perhaps they will be tied to the container, just do not remember. So remove at your own risk, knowing about how could these items be stored on the Internal map
[doublepost=1524621359][/doublepost]Example for cleaning:
[global delete where ParasiticPlant parententity = null rootparententity = null map = Internal
and for global cleaning:
[global delete where Item parententity = null rootparententity = null map = Internal
don't forget make save and backup before use this commands
