Greetings,

I seem to also be having a similar issue with the new version.

Re-pull the image or explicitly use the itzg/minecraft-server:java21 tagged image:

Newbie question, how do I actually re-pull the image? I'm using Container on a Synology NAS. I'm guessing I would run a console command, I do not see anywhere where I can edit specifically the image parameters within Container that would force it to Re-pull the image.

[itzg]

I'm not familiar with Synology NAS. You'll need to consult their docs or contact them.

[itzg]

...or just set the image tag, as I mentioned.

...or just set the image tag, as I mentioned.

Thank you I was able to get the server to work again!

[Shingoo2012]

wondering if anyone is having issues with the server have issues setting the new seed.

I sed my seed to 1234abc, the server loaded but when I went into the console to see what seed showed, it listed as 1511032834.

wondering if I'm doing something wrong, maybe a known issue?

[itzg]

Text seeds always get converted into the numerical equivalent, so I'm not sure if you're seeing an actual issue.

[Shingoo2012]

Text seeds always get converted into the numerical equivalent, so I'm not sure if you're seeing an actual issue.

Okay admittedly, my "issue" is that I'm learning some aspects of Minecraft I never knew before. In big picture I'm trying to find a new world to play with my kids. We have been using https://www.chunkbase.com/ (Java 1.20) to find a new seed. We enter in seeds like, 123abcd, JesusLovesMe2012, into chunkbase, and found the coordinates of an area we would like to use as our starting location.

When I put these seeds into the server config file, we boot up into a new world, I then transport to those coordinates we found on chunkbase, but its a totally different area than what chunk base generated. Also looking up the seed in the console and got a numeric seed instead of the alpha-numeric we entered in the file (makes sense based on what you said). BUT, in reverse, if I put the numeric seed value the server says I'm using into ChunkBase, I get a different world.

In the big picture, how can I properly use the Chunkbase page to "shop" around for worlds that I know will translate properly into the minecraft server?

I apologize as this discussion has evolved into a topic that probably belongs somewhere else.

[itzg]

Yeah this sounds like an issue to discuss with ChunkBase

If you could provide the container compose file or run command you're using I could try to double check syntax just in case that's it. And you are certain the server is being pointed at a fresh data directory to generate the world from scratch?

Please open a new discussion item (not an issue) when relying with any followup info.

[itzg]

@Triskelen is your original issue still valid? Can I close this?

[Triskelen]

I resolved it by rebuilding the container

So its resolved yes
