I tried installing this repo from the asset lib and manually.
The main branch has no core folder, so all the basic class_names are missing.
There's no such thing as hotbar.gd or others needed and this doesn't work at all for me.
Maybe I'm doing something dumb, but I have tried browsing and searching on github and there's none of the required class_name
After version 1.0 I transformed every core to a C++ module (on bin folder), they are included in the addon as a gdxtension library.
Test if you can use Inventory references (For example) in your code?
