Fixed a bug that would replace one player's menu with another's if both opened their menu.
Correction of errors occurring when the server is reloaded. Progressions were not being saved and quests were not being reloaded for connected players.
Added an error message when a quest cannot be loaded because it has been deleted from the file.
This is a significant update. If there are any problems, please report them.
I have normally updated the Wiki. If any information is missing or unclear, please let me know.
Also, I recommend that you reset your configuration file, to get the latest updates (saving the old one to reflect the changes).
If you like my work and want to support me, think about rating the plugin on its Spigotmc.org page and liking it. This will greatly motivate me!
