The plugin has been finally updated from using material IDS which have been removed since 1.13.2. It will now use material names instead of ID's
Added support for all new minecraft blocks to be used in towers!
Added a tower converter that converts your previous files that contain tower data using material ID to the new format. Hopefully, this will help you avoid needing to recreate towers, Though if you encounter issues, it is recommended that you reset towers.yml and recreate anything you had. (Backup your towers.yml before installing this version)
Added a safety check in loading boosters
Fixed a bug in towers command where towers with a space in their name were not recognized.
