For my 1.18.2 server I wanted to have this mod as well as Towers of the Wild. However, they are not updating their mod to 1.18.2. They have created a datapack instead here: https://www.curseforge.com/minecraft/texture-packs/towers-of-the-wild-reworked-datapack

The main problem with this is the loot table names have been adjusted. So the chests don't get a paraglider.

So I downloaded the your source code here and changed one line to get it working!
On this file The "loot_table_id" needs updated to: "towers_of_the_wild_reworked:tower_chest"

And unfortunately the "ocean_chest" seems missing from the datapack, so just that change worked for me.

yea this would be awesome :)

is there a datapack for this ? or a update ?

Implemented in both 1.19 release and upcoming 1.18 release.
