Frequency: Just now
World name: Louisoix
Character name: Sayumi Izumi
Retainer name: none
NPC name: none
Monster name: none
Class/Level: dancer 66
Party or solo: solo
In-game time: 16:30
Area and coordinates: Shirogane, x:9.3 y:11.8
Housing: plot 18, 23 ward
Steps:
1. I logged in as usual after the maintenance
2. Logged on my private plot that is just under my FC's (17 on the same ward)
3. Went to tend the plants of my FC garden and the house was not there. I clicked on the placard and it says it's on sale. On the residential area access it still says that the plot belongs to my FC.
4. I tried to configure the housing and it says that the plot is ours, but doesn't let me rebuild an estate because it says that there is already an estate built (but you can see it is empty)
5. I checked on my FC profile and it says that the plot belongs to us.

Please, give us the house back, we've worked so hard to get it...

It seems there will be another maintenance for that reason alone. Honestly I freaked out after reading your thread yesterday and I wasted no time in asking my FC to check on our estate and texted to my husband to check our private estate too. All still there safe and sound. I still see in your FC info on Lodestone, you still have your plot. Is everything ok now?

Only some servers will have their emergency maintenance related to certain housing data... your server Louisoix is one of them.
