I tried to use the 1.3.2 version of the origin mod as this was the only working version for 1.18.1, but all origins have three hearts or below (except for the giant origin published by minuturebob).
Am I the only one with this problem?
How could I fix this?

Do you have any other datapacks or Origins addons installed? If so, have you tried if it still happens with just Origins and Fabric API loaded?
