fix: Resolved an issue where the open spell was being cast by bots on despawned game objects. (#1842)

# Description

This addresses the infamous "Possible hacking attempt" error when bots
were furiously trying to interact with despawned game objects.
The problem was that the game objects were not being as spawned when
evaluating what the bot should do. It was only done when spells were
being cast on entities.
