If a host/server closes in Icarus, mounts usually do not stay active on that session; players are disconnected, and any mounted state can be lost or reset when the world ends. The reports I found also show mounts can disappear on disconnect, and dedicated servers are treated differently from host-based sessions, where the whole session ends when the host logs off.

What usually happens

  • If the host closes the game, the hosted session ends for everyone, so the mount is no longer present in that running world.
  • Disconnects while mounted can cause the mount to despawn or vanish, including the saddle and carried items in some reports.
  • Some players report recoveries or partial fixes only after reloading, rolling back saves, or using backup files, which suggests the mount state is tied to the session/save data rather than being permanently independent.

On another server

  • A mount does not reliably “follow” you to another server as a live, shared object.
  • If it was your mount and the game or server preserves the save state, it may reappear when that original world is reloaded.
  • If the mount was not properly saved, or if the session closed mid-state, it may be gone from that world entirely.

Practical takeaway

For Icarus, think of mounts as part of the current world/session, not as portable across servers. If the server closes, the safest expectation is that the mount will either be stored in that session’s save data or be lost if the disconnect happened at the wrong time.

TL;DR: when an Icarus host/server closes, the mount usually doesn’t remain active on another server; it’s tied to the original session, and disconnects can make it disappear.
