update v18.1

"Discord Suggestions" is a short series that will feature random prompts from
the #suggestions channel on our Discord Server.

The aim of this series is to chop down the long suggestion list, without
having to wait a specific theme. 

Each batch will last 5-10 updates and is planned on a bi-monthly basis (~)

See you and happy game-making! :)
