Helldivers 2 patch 6.3.1 fixes FRV crashes and voice chat bug

Arrowhead dropped Helldivers 2 patch 6.3.1, a small stability update targeting crashes and a voice chat bug that had been annoying players rejoining lobbies.

The patch knocks out five crash fixes: switching between fullscreen and windowed modes, cycling through vehicle customizations, button inputs in the vehicle customization menu, lobbies exceeding 32 unique vehicle patterns, and hosting a Geological Survey mission. On the miscellaneous side, the voice chat audio bug — where players couldn't hear each other after rejoining a lobby — is now fixed, and new players getting stuck finding their first mission is also resolved.

The update lands during the ongoing TCS+ community event, which Arrowhead framed as the reason to push stability fixes now — High Command wants every Helldiver actually making it into the fight. The FRV, or Fast Recon Vehicle, was introduced as part of Helldivers 2's vehicle content push, and the pattern-related crashes were a known pain point for squads who like to customize their rides.

No balance changes or content additions are in this patch — it's purely a stability pass. Players can check Arrowhead's Known Issues page for anything still on the fix list.
