Describe the bug
After not playing for a bit, I opened my world (singleplayer) and I was in the starter island. My inventory still had the items but everything else (including quests and advancements) got reset. I teleported to my known base coordinates (from an old screenshot) and it was just void. I opened the backups folder and it was empty.

Extra mods I added:
Draconic Evolution version 3.0.18.428

To Reproduce
Steps to reproduce the behavior:

1. Open the world

Expected behavior

My island and quests do not disappear randomly

Screenshots

Backups folder

Starter island (After it disappeared, I might have broken a couple leaf blocks, I changed to creative with Open to LAN)

Island before it disappeared

Same coordinates as image above, but after it disappearing

Quests

Additional context
Latest log
Log from before island disappeared
World file

I honestly have no idea what happened, nor have i seen a similar issue like this, maybe there was corruption with the world? honestly no clue unfortunately, especially with their being (for some reason) no backups
