Valheim Patch v1.0.21 Fixes Environmental Glitches and Launch Physics

Valheim patch v1.0.21 addresses erratic enemy jumping physics, weather intrusion indoors, and menu navigation issues. Crossplay remains active during the staggered multiplatform rollout.

Valheim patch v1.0.21 tackles various environmental bugs and interface errors. Because of platform restrictions, the update takes a few days to reach every system, though crossplay continues to function across versions.

Physics and Weather Fixes

Jumping on top of certain enemies no longer launches players away at extreme velocities. Snowstorms in the Mountains and Deep North, alongside ash storms in the Ashlands, no longer penetrate indoor spaces. Tree stumps in the Deep North no longer sway in the wind.

Interface and Vendor Corrections

The vendor interface opens correctly after players watch a cinematic during the current play session. Character and world name input fields now block invalid characters such as greater-than symbols.

Why this patch matters

This update cleans up several persistent environmental oddities and interface bugs.
