When an entity is removed from the scene all its scheduled updates also get removed via MyComponentFactory.RemoveUpdates. However when a single update is registered multiple times (usually as a result of a bug) this only removes a single one of those registrations, causing the component to tick after it is unloaded.

When cleaning up components during component unloading every update of those components should be removed, not just the first one. Note this will also require changing the tracking of scheduled updates in m_scheduledUpdateMap to be able to keep track of multi-scheduled items. Alternatively, MyComponentBase.RemoveScheduledUpdate could possibly be modified to always remove every scheduled update instead of just the first one.
