Unable to Remove Estate Hall from housing plot

Time: 12.23.2016
Frequency: always
World name: Jenova
Character name: Sky Pie
Area and coordinates: Lavender Beds ward 9, plot 6
Steps:
1. I was trying to relinquish my private housing plot and I have to remove the Estate Hall from it first. All the furnishing inside and outside are removed and no one has been inside of the house, on the plot or near it.

2. I got an error:
"Unable to renovate. A character is in the way"

3. There is no characters standing on the plot itself, fence, around the plot and no one is inside. I tried many times during few hours and it never worked. I also tried to close the game and re-enter.
Seems like there is a mistake that doesn't let me remove the hall.
I really need to get rid of my plot as soon as possible so I am sincerely hoping you can provide some assistance with resolving this issue!
Thank you!
