Unable to rejoin world without restart after connecting to subworld. #58
Description
tModLoader 2025.8.3.1
Subworld library version 2.2.3.2
The Stars Above 2.1.7.3
Description
When moving between worlds using SubworldLibrary with the Stars Above mod, returning to a previously visited subworld causes a SocketException. The subworld fails to load after returning to it. This happens both on a dedicated server and also via host & play from within terraria. The issue does not happen when playing single player.
Steps to Reproduce
Launch tModLoader server with SubworldLibrary and Stars Above installed.
Enter a subworld from the main world.
Return to the main world.
Attempt to enter the same subworld again.
Observe the error in the log; the subworld fails to load.
Observed Behavior
Subworld fails to load on the second entry.
System.Net.Sockets.SocketException: Cannot assign requested address occurs pointing to /tmp/CoreFxPipe_StarsAbove_Observatory.IN.
The first entry works fine; the issue only occurs when returning after going back to the main world.
Expected Behavior
Subworld should load normally each time, regardless of previous entries.
