Even after giving players the permission node towny.wild.item_use.* as well as nodes for each of the item IDs, the only people who can use any items in the wild are ops and people with the node ''. I have also tried the other node that was on one of the towny wikis (that I think was probably a typo), towny.wild.itemuse.
What perms plugin? As I know these knows work 100%.
I just tested 'towny.wild.item_use.*' and it's working perfectly.
What precisely are you attempting to do that isn't working?
Be 100% certain you are granting them the use of the full bucket and the empty one.
If you are still having issues drop in the IRC.
