Hello to anyone willing to help me with this. I've had a world with my girlfriend for two years, and today I attempted to restore the world (spigot 1.19.2) to a previous backup (paper 1.17.1) that I had already saved. I went into "backups" and clicked "restore server" next to my desired backup. However, when I joined the server, everything we had built was gone. The spawn point was different as if the server was reset with a new seed. I still have the paper 1.17.1 backup from about three days ago which I know must contain my saved world. However, every time I try to restore this backup, the same thing happens. Every time I click "restore server" next to the backup, the seed changes. Is there any way to fix this issue? Can I still access my old save without resetting the world? Please help, as we have built up this world for two years now and losing it would be a real pain. Thank you to anyone who can help.
