Somehow the forge server my brother was running was reset. We lost months of progress and are trying everything we can to recover the world. Last night something went wrong. He is not computer literate (and I'm not much better) but we were running the server on his PC, he said there was a power outage and believes that may have corrupted things. The strange thing is, it's the same exact world but all our stuff is gone and everything we built.
We were originally running Minecraft version 1.19 on Forge v41.0.91 but updated a few days ago to 1.19.1 Forge v42.0.1 so could install a dimension mod called Blue Skies
We played for a couple days without issue. However when he tried to start it today he said it didn't start and the server said some error. I went over to his place and looked at the logs. This first error in the logs is below. To me it seems like there was was problem saving?
[02Aug2022 10:41:19.688] [Server thread/ERROR] [net.minecraft.world.level.saveddata.SavedData/]: Could not save data net.minecraftforge.common.util.LevelCapabilityData@124967d3
java.io.FileNotFoundException: .\world\data\capabilities.dat (The system cannot find the path specified)
We tried to put an old backup in but that was from when we on our previous version so it wouldn't work. When we tried the newest one again the server immediately started "Preparing World" for longer than usual and sure enough the world was reset and all was gone...
Any help would be very appreciated. I have all the logs and can post all of if needed. Below is a Github link to the full server log that shows the error(s).
