Once Human 3.1.1 Fixes 7 Bugs, With 9 More Due by 08:30 PT on Oct. 23
The scheduled batch includes a lower Team unlock threshold and compensation for lost Halloween Wonder Night attempts, while crocodile-pattern losses are planned for the Nov. 5 version update.

Once Human’s Oct. 23 Version 3.1.1 notice confirms seven issues fixed and schedules another nine for 08:30 PT. Starry Studio warns that the actual completion time may vary. The scheduled changes include fixes for mod effects, ship placement, and Halloween Wonder Night progress, plus an earlier unlock for the Team system in Isles of Abyss, according to the October 23 Steam announcement.
Two problems still marked for urgent repair in the Oct. 22 3.1.1 notes are now among the completed fixes: characters moving aboard ships could experience lag or position rollback, and the Walkman could play songs without sound.
Two other issues remain outside today’s fix lists. The Calamity Owl can still clip underground in strongholds, and the developers say crocodile patterns lost when transferring out of Eternaland need model changes and are planned for the Nov. 5 version update.

Notice on Frequently Reported Issues:

Regarding the issue where the Calamity Owl in strongholds abnormally clips into the ground
We have received numerous reports from players that the Calamity Owl in strongholds may get stuck underground while moving, preventing players from attacking it normally. This issue is currently being addressed, and we will complete the fix as soon as possible.
-
Regarding the issue of crocodile patterns being lost when transferring out of Eternaland
We have received numerous reports from players about the issue of crocodile patterns being lost when transferring out of Eternaland. We have identified the cause of this issue; however, since the fix involves some model changes, it will need to be completed with the next version update (November 5).
