1. If you are using mods, this could easily account for such issues. Remove mods if that's the case. If still corrupt see points below.

2. If the seed you're playing on and the tames are from before more recent additions to the game, it could be that this is not possible on that seed and you'd need to make another(you can have same seed more than once in your map choices just give it a different name to be the more current one.

3. If none of that's the case, then try making a new seed(not same seed id) and seeing if the same thing happens, if not it may have been a bad seed.

4. Remote possibility to try but go to valheim in your steam library and click properties then verify local game files to make sure there wasn't a corrupt download causing the conflict.

5. If all fails, then report the bug in the bug subforum area and perhaps consider fully reinstalling the game as a last resort.

Before you do #5 you should try a "clean" install.

Uninstall game

Manually go to folder and delete the whole folder.
Any files not recognized the game as game files will be left behind, any mod or corrupted files will be there and pollute your install again... You MUST MANUALLY delete the whole game folder.

Reinstall game making sure you don't have any mod managers running.

Mod managers have also been reported to re pollute your install just by being there on your computer... if a clean install will not work then do the process again after you uninstall any mod managers.

If after uninstalling any mod managers and doing a clean install it still won't work THEN submit a bug report and state all that you did to try to resolve the issue.

A clean install is important for the bug report as it will assure the devs that it is the game and not some garbage left over.
