Describe the bug
I am using the Fabric of Life modpack, but when I try to use this on a server this mod stops working.
Does anyone have an idea of how this might happen?
It does work on a single player instance, and the mod is installed on the server.

To Reproduce
Steps to reproduce the behavior:

1. Load the Fabric of Life modpack on a server
2. Fail

Infos:

• Minecraft version: 1.16.5
• Mod version: 2.11.4
• Fabric version: I don't actually know, nor know how to find out

If you provide a crash report please include it in a readable way (like pastebin or gist for example).

Can't reproduce with just FallingTree.

Either:

• You have a configuration on the server that deactivate the tree breaking / invert sneak / ....
• One of the other mods makes it incompatible server-side

If this is the latter I'll be long to find with pair of mods brings the problem. The easiest is to shrink the mods by 2 each time.
So for example:

• Start minecraft with half the mods (FT included), if it bugs, then the pair of mods is in that half list. Other wise it is in the other.
• Keep only the half that has the incompatible mod (and always keep FT)
• Repeat

If you have 100 mods, repeating these steps 7 times should be enough to find the 2 mods that together are incompatible.
