After updating the mod to the 0.12.0 version, i have an error message pop up at the start saying that the config file could not be found, and in game the skill tree is not showing with the error message "it seems there isn't anything here", look at the screenshots below:

The mod is not working anymore, i had additional hearts that now got removed

Edit: Just saw the closed issue on this github with same issue and the fix was to download the attributes mod, just downloaded it and everything is back to normal so thank for the help i guess. Closing the issue.
