Title: Why are Royal Elderberry seeds untradable, if you can simply exchange them using a chest ?
Reproduction Rate: 100%
Blocker? No
Details:

• Not exactly clear why anyone went through the effort to mark certain items as "not tradable" if all you need to do to exchange the items is drop them in a shared chest, thereby trading the object in a round-about manner.
• Take the "Royal Elderberry Seed" for example: I cannot directly trade the item, however if I place the object in a chest, the other player can simply pull that object out of the chest.
• 
  
• Sounds a little bit of an effort to trade something I was not aware was untradable to begin with.
• The "Immortality Fruit Seed" has similar restrictions.

Steps to Reproduce:

1. Acquire two players
2. Have Player A acquire "Royal Elderberry Seed", and place it in their inventory
3. Have Player A initiate a trade with Player B
4. Attempt to drag the seed into the trade window.
5. Observe the error message that appears.
6. Now have Player A acquire a lot
7. Set the permissions for the lot so Player B can move objects.
8. Have Player A acquire a chest (I was using the Ornate Public Cache Chest, but I'm sure any chest will do)
9. Have Player A place the seed in the chest
10. Now have Player B extract the seed from that chest

"Well, that was a little bit tedious."

 

@Duke Raas Bug submitted.

 

Very very tricky for finding an implicit trade system through the use of a chest . I have updated the behaviour on the client and server to prevent placing no-trade items into publicly accessible chests. This will ensure that items are not able to be passed to other players if they are not intended to do so. This will go out in the next patch.
