Once Human has repaired Thermal Tower Tech unlocks for players who transferred from the old Way of Winter scenario to the new Way of Winter Permanent Server. The developer lists that specific migration path in its September 23 bug-fix notice for version 3.0.6.

If that move left the new technology unavailable, check the tower's unlocks again. The notice does not announce different transfer requirements.

A separate fix addresses territory portals that occasionally failed to work or appear. Retest an affected portal after updating.

The short announcement provides no separate platform rollout times or special recovery procedure. Its confirmed scope is the Winter technology unlock and the intermittent territory-portal fault.
