Having serious rubber-banding after server updated this afternoon. Server currently unplayable. Been using Survivalservers for years on several games. I am confident they will resolve the issue as quickly as they can. New games can be expected to have issues. Valheim was a lagfest early on.
I don't have Valheim+ installed. Never said I did. I figured it out though. Your server is updating the public test version as default. So I had to update my client to public test to work.
