The issue with the shop has been discovered and will be fixed asap. As for the buy signs, those will be added as soon as KGBTech (One of our staff) gets online. He's been pretty busy so let's be easy on him.
Crates and voting perks will be setup soon, need to discuss things with Tomo before I attempt to set it up. I've also been thinking about setting up dungeons across the map for players to raid, and fight a boss. This can all be done with command blocks, and it most likely will be.
