When playing on a 1.18 server with a 1.17 client, rain appears in snowy and dry biomes if there is a cave biome below the surface biome.

As stated above, when you use a 1.17 client to play in a 1.18 server, it will cause rain to appear in snowy and dry biomes if there is a cave biome underground.

To reproduce:

  1. Join a 1.18 server that has rain enabled using a 1.17 client.

  2. Locate a snowy (snowy taiga, ice spikes, etc.) or dry (desert, savanna, etc.) biome that has a cave biome (lush caves or dripstone caves) underneath it.

  3. Wait for it to rain.

  4. When it rains, observe the type of precipitation and compare it with the surface biome.
    β†’ ❌ It will rain when it should be either snowing or not raining.

I suspect that this is a client-side problem because weather works normally when you use a 1.18 client to access the server and because the rain resulting from this bug does not make any sound.

I took the snowy plains screenshot while playing on a 1.18.1 server with a 1.17.1 client. As the screenshot shows, the client displays snow on certain blocks and rain on other blocks, although it is snowing on all of these blocks according to the server.

How can you join a vanilla 1.18 server with a vanilla 1.17 client?

Many servers have plugins that allow clients from multiple versions to access them. I do not know the inner mechanics behind this particular server, but it seems to me that they use these sorts of plugins as well, so even though the server is on 1.18.1, I can access it with a 1.17.1 client.

if the bug can't happen without plugins, it's not a vanilla bug and can't be fixed by mojang

Thank you for your report!
However, this issue is Invalid.

Your game, launcher or server is modified.
If you can reproduce the issue in a vanilla environment, please recreate the issue.

  • Any non-standard client/server/launcher build needs to be taken up with the appropriate team, not Mojang.

  • Any plugin issues need to be addressed to the creator of the plugin or resource pack.

  • If you have problems on large servers, such as The Hive and Hypixel, please contact them first as they run modified server software.
