Aren't there usually 2 Server jars on the snapshot pages? I think the regular server jar isnt there, and we are all using the cross-platform one presumably for windows 10 version?

Douglas James 2020-05-13T17:26:19Z

Bumping this error

violine1101 2020-05-13T17:33:09Z

No need to bump. It only clutters up the comments section.

@@unknown The server jar is universal to all platforms.

@everyone The issue is now complete. There is no need to comment any further on this ticket. Thanks.

Pavel Adamov 2020-05-13T17:40:01Z

So by complete do you mean fixed or not cause I can't even go back to 20w19a

skyrising 2020-05-13T17:55:01Z

Results from code digging:
the static field MinecraftServer.DEMO_SETTINGS now loads WorldGenSettings.DEMO_SETTINGS,
WorldGenSettings loads FlatLevelGeneratorSettings which loads structures/features.

As a result of that things are initialized in the wrong order because all of this happens before Bootstrap.bootStrap() in main()

Simon L 2020-05-13T18:32:11Z

Bootstrap.bootStrap() should be called at the start in the constructor, should be an easy fix. For now a fabric mod that fixes it is already here, in case you don't want to wait. https://github.com/haykam821/Two-Zero-Bee

Mike Dedmon 2020-05-14T01:11:18Z

I've installed the fabric as instructed and still crashing. I see it load the Fabric API and the twozerobee mods as expected, but it still crashes with the same error.

I'll probably wait until the next release is out. I'm not that important that I need this to work right now, but wanted to document that it didn't for me. Thank you!

sounds like you forgot to add the mod, and twozerobee does not require fabric api

Teah-Jay Cartwright 2020-05-14T08:24:15Z

Says Fixed, but I just downloaded the server jar and it is not fixed, or the link has not been updated.

Warren Liddell 2020-05-14T09:01:10Z

Thatd be because the new B version of the snapshot hasnt been released yet.

@Devan S. - Thanks - I derped. Put the mods in the wrong folder. 😞 Thanks for the clarification. I'm up and running now.

To keep this bug report on topic, can I ask that issues related to Two-Zero-Bee GitHub please be placed in the Two-Zero-Bee bug tracker. This is a Mojang tracker and should be treated as such.

To that point, 20w20b is now released (under previous URL) and available for immediate download https://www.minecraft.net/en-us/article/minecraft-snapshot-20w20a.

Note the comment at the top...

Edit: We've now released 20w20b to fix a bug.
