Describe the bug you're experiencing

Using MultiMC I add the mod as usual.
Launcher loads fine, but when you try to load a world or a server, it hangs on the Joining or 100% Screen, and MultiMC throws a load of errors into the log.
I have pasted a short section of these errors below.
If I remove the Farsight mod and reload the instance, all is fine.

Other mods running: Entity Culling / Fabric API / Freecam / Iris / Lithium / Sodium / Xaero's Minimap / Xaero's World Map

You may have to fix your mods because the game is still logging to files and likely wasting hard drive space at an alarming rate!

Reproducability

As above, loading a world with Farsight active causes crash.
