I'm the only guild leader ROTE has ever had. I created the guild, bought the neighborhood, bought the plot and palatial guild hall and placed it. When guild halls were messed up 2 or 3 years ago for many many guilds across most servers the original neighborhood is now listed as 3 out of 4, but as you probably know, the guild neighborhood officially belongs to the guild, not one person, and I think the same is true for the plot.
Ya - I wasn't sure if you were the only one ever, figured as much but i know that specifically gave us trouble so was worth mentioning. hopefully they can get you patched up. We finally have a TR neighbourhood back ourselves as of just last week for the first time in many years after the whole neighbourhood went mysteriously missing. i haven't moved the guild hall over though for fear of disaster.
I ran a script to add the missing items back to the hall. They will be marked as Stored, and if you load a saved layout it should place everything again (admittedly after a bit of lag). Sorry it took so long to get the items back. On the bright side, there was a clue about why this is happening and gives me some hope that we will eventually fix this. If there are still issues after the items are restored, please send me a PM.
