[Bug] Achievements are broken when updating to the new version

[CalaMariGold]

Expected Behavior

Using Triumph, we have a bunch of custom achievements and we disable many mod achievements.

Actual Behavior

Animania breaks Triumph and none of our custom achievements load.

Steps to Reproduce

Install animania, farm, extras + triumph and make custom achievements. Or just clone https://github.com/Rebirth-of-the-Night/Rebirth-Of-The-Night and test it yourself

Version of Minecraft, version of Animania, Single Player or Server

1.12.2, base-2.0.0.23, single

Screenshots encouraged

Oh dear, that's bad... I had to do some bad stuff to get the addon advancements working, seems like I broke everything else in the process...

@Tschipp Is it possible there may be a temporary fix? Maybe a config to disable all animania achievements? We'd love to be able to update to the latest Animania version but this issue is holding us back

[Tschipp]

I need to do further testing, I hope I can find some time soon

Bump, still an issue on the latest Animania release.

Thanks <3

Bump, still finding this to be an issue

I'm also having this issue. I second the request to make Animania advancements optional; I didn't even realize there were any.

And when server tries load advancement when someone have some achievement so it's just crash.
