+Subject: [PATCH] force entity dismount during teleportation
+
+Entities must be dismounted before teleportation in order to avoid
+multiple issues in the server with regards to teleportation, while
+we now lose the ability for plugins to monitor this specific case
+of entity dismount, the alternative is that we allow a cancellable
+event, but silently ignore the cancelled status, which might cause
+further issues for plugins tracking state
+
+Given that nobody can be relying on the Cancellable state of those
+events during teleportation due to the issues that arise from this,
+this is a small trade off
