I checked this against the real v83 client data, and the "can't open it" part is how the original game behaves too. The Pot has no use action at all — the entry that gives an item a double-click verb simply isn't in its data, so double-clicking it does nothing in v83 either. What the Pot does have is a replacement entry: when its timer runs out it is swapped for item 4001334, the bloomed yellow flower, with the message "the flower bud opened wide and a yellow flower came out". So "watch it for 30 minutes" is meant literally — you leave it in your bag and it turns into the flower on its own, with no clicking involved. What's true is that we don't run that swap yet; nothing in our build expires or replaces an item, so the Pot will sit there forever. I'm closing the "can't open it" part as working as the original does, and I've written the timed bloom up as a separate piece of new work rather than a bug in the click. Worth knowing: the reference server we follow never implemented it either, so we'd be building it from the client data directly.
