Hello! Sorry for my english:

The effects of flag " potion-intensity:" keep in the player before go out of the precious stones.

And the stone with flag "confiscated items" works, but if the item have a lore, the lore is lost when the items are refund to the player.

Thanks

Nothing I can do about the confiscated item unfortunately. Best thing would be to remove this item from the confiscated list. There is a new flag I have added that helps with this, its called the "unusable-items" list, it is similar to the confiscated-items list only that instead of removing the item from the inventory, it will move it to a slot outside of the hotbar thereby preventing the users from using it. This may be better for you.

@phaed420 Thanks for you fast anwer. But im use the plugin "BroomSticks" for use shovel fell like brooms. ¿How make for when a entry in a region of PSstone the people can´t use brooms?

Add the broom id to the "unusable-items" list.

@phaed420 oh, i try! thanks!!

And what happen with the potions effects? have a solution?

No solution for that, I\ll have to look into it at a later date.

@phaed420 Thanks! And please tell me how write the confiscated items:
