MysticalQuests 1.2.0
Feature Updates
- Added quest stages: Now quests can have multiple stages, each one with its own type, condition, reward, goal, and more. Please note that the configuration has been refactored to accommodate for this, and old configurations are no longer supported.

Bug Fixes
- Fixed an issue where the Mongo connection wasn't closed properly.
- Fixed an issue where the example category file was reading values from the default state instead of a modified one.
