I'll leave it written here even if i already wrote it on the mod page as well.

Those mods seriously need an update to the latest minecraft version.There are many cool mods on curseforge that did not receive an update to 1.16.5 version of minecraft and just stopped updating to the 1.12 version,this one being one cool mod but many peoples moved on to newer version.

I know it should be a lot of work but an update would be very much apprecciated and i saw others peoples proposing it on the mod page.
