I've posted in both the discord for domestication innovation and in the discord for sprout that currently it appears the newest versions of both mods (linked below for clarity) seem to run together but when both are active the sprout elephants do not function properly. They can be tamed and gather water but will not spray water as intended. The weirdest bit imo is that they do not seem to be using the same commands sit/stay/follow as other creatures so I am not certain why the issue occurs myself. But I am attempting to bring it to both modders attention in the hopes one or both can fix it!
