“A long list of tweaks and bug fixes incoming today! It touches on a little bit of everything, and we hope this patch will serve to give you all a smoother experience adventuring in Valheim.”

From the developer's post

Read this first

  • Due to some internal restrictions, the patch will require a few days to get uploaded to all platforms. Despite this, however, crossplay will still remain functional, so you can keep playing with your friends regardless of what platform you’re on.

What changed

Combat

  • Added a fix for being yeeted at high velocity when jumping on top of some enemies
  • Fixed bug where the “No Skill Drain” status effect could get re-applied after the timer ran out

Building

  • Snow storms in Deep North / Mountains and Ash storms in Ashlands no longer blow inside of your house

Deep North

  • Tree stumps in Deep North no longer sway in the wind
  • Make snow walls part of DN locations (e.g. village) easier to destroy
  • Trees in Deep North now drop Timberwood cones, plant them in more hospitable biomes for a humongous tree (that also drops more Timberwood)
  • Tweaked Timberwood drop rates, now drop fewer pinecones and more Timberwood

UI & settings

  • Fixed vendor GUI not opening after having watched cinematic in the current session
  • Fixed a bug where UI fields for names (World and Character) allowed non-name characters (e.g. ‘>’, ‘<’, ‘|’, etc - are no longer allowed).
  • Items no longer drop outside of inventory on mouse up
  • Fixed bug that could cause Credits to show up on top of main menu GUI when exiting End Credits cinematic by pressing Space

Items & loot

  • Fixed bug where two trinkets could be equipped at once when dropping trinkets from itemstands
  • Record correct crafter of item when Frost Foundry is network-owned by another player (achievement progress for crafting achievement is still tied to network owner, requires network incompatible update and is coming soon™)
  • Made Baked Poteitr, Kale Chips, and Oven Pancake craftable at Food Preparation table instead of Cauldron
  • Correct tooltips are now used for uncooked Baked Poteitr, Kale Chips, and Oven Pancake
  • Removed requirement of moose trophies for upgrading DN mage helmet

  • Decrease Kall Fimbulbringer’s screen shake on some of his attacks
  • Decrease Kall Fimbulbringer’s Yagluth Aspect’s Fire Nova DOT by half (ground fire)
  • Made moose colliders more accurate to the moose body
  • Decreased Moose attack ranges somewhat

Terrain & world

  • Fixed graphical seams in the ocean
  • Make some previously indestructible props part of some locations destructible

Stability

  • Fix a bunch of rare crashes, mostly in multiplayer
  • Fixed an issue with save caching where file status can get out of sync when a world is modified outside of the game
  • Added a retroactive fix that cleans up character and world files with invalid names (e.g. “i<3” will be removed). Fixes critical bug that causes UI in main menu to disappear when selecting “Start Game”.

Achievements

  • Fixed a bug where some achievements were incorrectly tied to the current difficulty level - Mighty Halls, Comfort is King, The Homesteader, The Architect, and The Survivor.
  • Add Troll Trophy as requirement to The Trophy Collector achievement
  • Fixed a bug where the Achievement details panel could not be scrolled via Touch

Controls

  • Fixed a bug where you couldn’t filter Boss or Death markers with Gamepad
  • No longer show Gamepad association UI on startup

Audio

Performance

  • Frozen Skeletons and Greydwarves no longer LOD out of existence super early

Multiplayer & servers

  • Added info popup to when trying to join crossplay server while “PS5 only” toggle is on

Will your old world still work?

Worlds created before 1.0 keep working and keep receiving new content, but 1.0 changed how terrain is generated. See save compatibility by version before you update a world you care about.
