SpellFixes
by GrippyGoater
SpellFixes is a server-side Fabric patch for 1.20.1 that addresses a crash when Spell Engine and Invoke SpellBlades spells interact.
What it does
Players who cast a particular spell from the Invoke SpellBlades family could bring the server down, with a crash log showing a server thread error during a spell invocation. SpellFixes targets that compatibility problem so the spell can resolve without stopping the server.
The patch is server-side only, so players join without installing anything. It is built for Fabric and published for 1.20.1 only, under All rights reserved, and is not open source.
Key features
Crash prevention
Stops the server crash that occurs when a specific invoke spell is cast while the Spell Engine is active.
Entity lookup fix
Resolves the entity lookup failure that happens during casting, so the spell finishes instead of halting the server.
Spell casting stability
Keeps spell invocations from interrupting the server thread during play.
