It's all gone

This past week I had to reinstall windows because my PC was having some issues, and just now I decided to get back into Valheim. Turns out, yes, the saves on my C drive are all gone, naturally, but for some reason the saves on the Steam cloud aren't much good either.

Instead of saving my main world, and the one I last visited, not to mention the one I visited the most, the only world save on my Steam cloud is one I made just to collect raw materials from, with boosted resource drops. I guess it's based on the most recent world made?

The character save seems to be good, except for the fact I had a few inventory mods so I'd have to update those mods so I can load it without the game thinking all the stuff in the extra slots don't exist. Or I could revert the game version to pre-1.0.

But my villa, with the penthouse suite, and the castle walls with the wooden hoardings, not to mention all my portals and outposts, all gone.
