Ignore the guy above; you can still play with mods. [EDIT] By "guy above," I don't mean avatar.zero, who's giving very sound advice.

However, the ValheimPlus mod is out of date, so you will need to either replace it with a fork (ValheimPlus Grantapher is recent) or use alternatives to V+ entirely. I suggest the latter as the best move, but using the temporary fork should solve your problems for now.
