Hi there.

I am running 1.15.2 under multimc 0.16.11. This error is from the latest alpha version but I got the same error from the previous ALPHA (0.13.394).

I'm not sure what's going on here or if some configuration settings have changed.

I note that the naming convention for the alpha releases has changed. Previous to the last two releases, they were in this format: minecolonies-0.13.379-ALPHA-universal.jar and minecolonies-0.13.358-ALPHA-universal.jar. I don't know if that makes a difference.

Hopefully, this is the right place to post this.

You're using the wrong file. - API is for modders.
