Describe the bug
A siege was going on with a town, and then the attacker placed a white banner to surrender. After all 7 battle sessions had passed, in chat it said that the attacker had successfully abandoned it and that the town was saved.
The town's name no longer appears as a tab-complete option with the command /sw hud, however, if you still input the towns name yourself, using /sw hud TownName, it shows the hud for the siege, with the Siege Status being "Attacker Abandon", as shown here:

Also, when attempting to break the banner that was used to start the siege, it acts as if the banner is being used for a siege assembly:

To Reproduce

1. Start a siege on a town.
2. Wait 24h to be able to surrender the siege.
3. Place the white banner to surrender.
4. Wait until all 7 battle sessions have passed and the siege "ends"
5. In chat it will say that the attacker has abandoned it and the town is saved.
6. Try to break the banner, it doesn't let you, and says there is a siege assembly in progress.
7. Try doing /sw hud TownName, and observe that the command still works, instead of saying "Town TownName does not have any active sieges" like it should.

Expected behavior
The siege should have ended, the banner should be breakable and the /sw hud command for that town should return "Town TownName does not have any active sieges".
