Just finished my store at the /warp mall, but I can't seem to get the item to show in the item frame after finishing the sign. Is there a specific thing, that I'm missing, to get the item currently being sold to show in the item frame, just like the other shops??
In a mall shop (unlike the other shops you had) you have to manually place the item in the item frame, like you're decorating your own place. Bonus points for renaming the item so that the word shows up when someone hovers over it.
You get sneaky! You rename the item in an anvil to its actual name. You can also add tags and such to change the color. When I see you online next, I'll show you.
