What happened?

When I try to load my world with swem it crashes with an exit code of -1. It works perfectly fine with my other mods, so I'm sure swem and geckolib are the issues. I have tried updating my optifine (which didn't matter anyways because the game still crashed after removing optifine) as well as backdating my forge to the recommended version and switching to the latest version.

What should happen?

My world should load without crashing.

This is due to a corrupted horse data file.

You can navigate to world/server folder -> serverconfig -> swem -> Then delete the horseData.json file.
This will make you loose tracking, if any was made.
A fix is coming in the next release.
