The Hidden Temple Roof & Stairs pack was introduced to the Store with patch R32 on June 16th 2016.
This pack includes:
Plus one kit of following blocks:
Store-bought recipes are available on all Creativerse worlds (will always "carry over") after being bought once.
Additional to the crafting recipe you now can claim one block kit (that includes a number of examples of all blocks from the pack and 1 extra) on one Creativerse world of your choice.
The crafting recipes from this pack cannot be unlocked other than via Store, even when you receive the blocks themselves from other players who crafted them. Currently these blocks can currently not be obtained on any Creativerse worlds except than from other players.
