Regarding Saves and New Updates

[GDHO]

In regards to saves and new updates going forward will there still be server wipes. I played this game a long time ago, but I always ended up stopping because I'd be in the middle of a build only for my work to become obsolete. I recall a system they were going to implement where they leave old worlds alone and only update new ones is this implemented yet?

Since there are no company servers, only private ones, unless you delete your savefile there will be no wipes. However, there have been patches that made buildings fall apart. I'm sure devs try to avoid changes like that but for example new patch (in beta) adds two new workbenches (one is used to create items that used to be in a different workbench) so that may affect your base layout.
If you play alone you can go in Steam into right clicking your game -> Properties -> Betas and set your patch, disabling steam update feature if you are really afraid of losing your progress.
Personally I've been playing for last couple weeks with no problems and patches are not too often (2-3 a year?) and the update that is in beta is rather small, so you can either start now or wait for that patch to leave the beta and then you should have at least couple of months of peace :D

I think Point 3 is where you need to look for your "wiped" game saves.. I dont multi play so i cannot speak personally about MP.

Hoja is also correct a recent update "Ashlands" changed the worlds edge Height map. so people who had built in/near that area had buildings that dissassembled since they were no longer on the ground (as i understand it) closer to the centre nothing changed


So world files are in 3 (at least places)

1) Single Player using January 2023 versions and beyond
C:\Users\***\AppData\LocalLow\IronGate\Valheim\worlds_local

2) Single Player using Steam cloud saves here
https://store.steampowered.com/account/remotestorage

3) now Single Player and Multi Player ALSO apparently save to here:
C:\Program Files (x86)\Steam\userdata\yourSteamIDnumber\892970\remote
