Dune Awakening 1.5.3.7 Repairs the Unstuck Button
The October 9 hotfix targets an Arrakeen collision trap and an Unstuck failure in both social hubs. Steam players need a client download.
Dune: Awakening's October 9 hotfix targets a specific frustration: getting stuck in a social hub and finding that Unstuck will not get you out. Version 1.5.3.7 fixes an antenna collision spot near the Atreides Residency in Arrakeen, along with an Unstuck failure affecting Arrakeen and Harko Village.
It is a small repair, but a useful one if either problem has interrupted your session. Steam's announcement says the hotfix requires a client download. Restart Steam if the update does not appear automatically.
Two fixes, both tied to the social hubs
The Arrakeen change addresses a particular antenna stay near the Atreides Residency. It is not a claim that every place where a character can become trapped has been repaired.
The second fix concerns the Unstuck button itself. Funcom names both Arrakeen and Harko Village, so that repair covers more than the single antenna location.

Check the update before returning
Make sure the client has downloaded the hotfix before trying the affected location again. The announcement does not promise recovery of lost progress or a general repair for every save, building, or connection problem.
If you remain trapped after updating, note the location and installed version when contacting support. Those details help distinguish the reported fix from a different collision problem.
