tModLoader (Calamity) World fix?

[Lytrify]

(Calamity) So i was playing on a modded server and i turned it off and turned off the pc, next day i turned on the server but when i joined everything was fine until i noticed that all the modded blocks and biomes were missing, exept the ones in my inventory and in chests.

The sunken sea, the abyss, the sulfuric sea were all gone also the metal laboratories were missing with just an empty space instead.
All bosses, entities and npcs still existed and were summonable. Any fix?

I don't know about a fix and I don't know if this may help you, but sounds like you're missing the .twld file.
Terraria stores vanilla info (e.g. tiles) in a .wld file, and tModLoader stores the mod info in the .twld file. That's where the Calamity blocks and that stuff should be. Look into C:\Users\yourusername\Documents\My Games\Terraria\ModLoader\Worlds\Backups to see if you have a backup of that .twld file. Good luck!
