Hello, Engineers!
After carefully evaluating feedback provided by the community, we have decided to make a major change to the functionality of the Decorative Pack. Soon, all players will be able to interact with these blocks regardless of whether they own the Decorative Pack or not. In the case that a player doesn't own the Decorative Pack, they will just not be able to build with these blocks. This change will be made in an update releasing in the coming weeks.
Cheers! ːsteamhappyː
