Subject: [PATCH] Fix off region raid heroes

This patch aims to solve a potential incorrect thread call when completing a raid.
If a player is a hero of the village but proceeds to leave the region of the
raid before it's completion, it would throw an exception due to not being on the
same region thread anymore.
