Description of the Bug Encountered

Edit: Please read the comment first, the issue is basically solved.

In advance: I'm not sure if it's becuase of Wilder Wild or Friends&Foes, but it worked fine with Wilder Wild's older version 2.4.6. on fabric 1.20.4. (Loader version 0.16.5)
The error on startup appears since Wilder Wild 3.0.0 through 3.0.2
Changing to an older Friends&Foes version doesn't help.
Latest Java 8 (8.0.4310.10)

Additional context
If it's because of Friends&Foes, I'll gladly forward it to them.

Thank you very much!
Kind regards,
Martin

Sorry, forget that. FrozenLib was missing. But shouldn't there be a message on startup, for the specific mod that's missing?
And bonemealing a maple sapling just spawns leaves.

??????

Wtf is going on

Not only is the first part confusing because the issue is a FrozenLib’s java thing not matching 1.20.4’s (which I tested and it was fine,) but then maple saplings only spawning leaves??? what?

Can you send a screenshot for the maples?

Please try launching the game with a Java 21 runtime for now.

Sorry for the confusing report. In summary:

The problem was just that FrozenLib was missing. (Installing the newest Java update didn't help)
Idk why it said in the crash report, that Friends&Foes was the problem. But usually the launcher informs you on startup, if a mod is missing. Strange, that it didn't notice me for the missing FrozenLib.

The thing with the maple saplings happens, when there is not enough space for them to grow. The saplings just disappear and then spawn the leaves instead. (Make sure that the grass is not covered with snow, etc.) I didn't notice that there wasn't enough space before and thought they just spawned leaves, lol

But when testing, I've found a way worse bug: When growing a maple sapling on a SERVER (same Java and fabric version), after around a minute, you get the following error attached below and your client crashes. You can't rejoin the world anymore and restarting the server also doesn't help. Just a backup works, where the tree isn't there. The server itself doesn't crash or give any helpful info, when the client leaves.
I'm now 100% sure it's because of the maple tree, because I tested it 3 times: After waiting around 15 minutes and nothing happening, I then grew the tree from bone-mealing the sapling, then the crash happens around a minute later.
(Note that the report says something about a physics mod, but that mod wasn't installed anymore)

crash-2024-10-28_18.16.30-client.txt
crash-2024-10-28_18.22.53-client.txt

That’s a lot of mods 😭
In any case, would you be able to try this with 3.0.3? It hasn’t fixed the saplings only generating leaves, but might fix the crash.

Maple sapling issue fixed in 3.0.4

Does this still occur with version 3.0.4?
