Island rollbacked

[Nightkriss]

When I logged in today I discovered that half of my island is gone. I'm not sure but it looks like about 3 days old.

Your Name: Nightkriss
Island Owner Name: Nightkriss
Coordinates: X=-15176 Z=-14402 y=144(9)
Time/Date (Post a time/date when everything was fine): 13.10.2017 around 23h-00h CEST ( can't remember exactly when I logged back, but definitely earlier than 01:00 14.10.2017)
Description of Issue: Looks like my island reverted to the state it was few days ago. I lost my spawn/grinder farm, 32x32x48 Bigreactor and few other things. In My alloy smelter were darkened glass(blocks light) so it's definitely just a sec before I started messing up with Cursed Earth
Screenshots (Optional): 

 

I don't want my island to be rerolled. I'll try to redo everything from scratch. Now that I've the precious experience to make it better and faster.
