had a power outage hit yesterday while some friends and i were playing. soon as i could get back on alot of terraforming done was undone(chunks respawned) and some random chunks were completely removed with a void in the bottom. One of my friends house they been building for weeks was completely despawned and the mountain was rebuilt where the house was. its our main world if there is anyway to backup or salvage this to before 4pm central time on 6-6-2021 would be grateful.
