FAQ & Troubleshooting

Right-clicking the spirit doesn't catch it

• The jar must be empty (no "Contains: …" on the tooltip).
• The spirit must currently have the Crusher job. A spirit set to another job, or one that hasn't been assigned a job yet, is ignored.
• It must be a Foliot / Djinni / Afrit / Marid. Other Occultism spirits can't be jarred.

The input slot won't accept my item

The trapped spirit has no occultism:crushing recipe for that item at its tier. Check in JEI: look up the item, open the Crushing category. If there's no crushing recipe, the jar can't take it. Raw ores and most metal chunks work; processed items, tools and plain blocks don't.

It stopped crushing

• Output full. If neither output slot can hold the next result, the jar pauses until something pulls the output.
• Input ran out. Obvious, but worth checking the feeder.
• Recipe gone. If a datapack/modpack removed the crushing recipe for that item, the jar stops on it.

It's too slow / too fast

Speed is Occultism's per-tier timeMultiplier times the mod's jarTimeMultiplier. See Speed and Output for how to change either.

Can I move a working jar?

Yes — break it. The spirit stays inside the dropped item (tooltip still shows it). The input/output contents drop as loose items next to it. Place the jar back and carry on. See Crusher Jar.

I broke the jar and the spirit is gone!

It's not gone — it's in the jar item you picked up. Place the jar and it's back, or release it with the Demon Extractor Blade.

Does it need to be on the server?

Yes. It's a side = BOTH mod — install it (and Occultism) on both the client and the server. The crushing logic runs server-side.

The screen opens on a normal right-click / doesn't open

It opens on sneak + right-click with an empty hand. A plain right-click is deliberately a no-op so you don't pop the screen while building next to it. Holding the Demon Extractor Blade makes right-click release the spirit instead.

Multiplayer: someone else's jar shows the wrong spirit / no portrait

Make sure client and server run the same version of the mod, and that renderTrappedSpirit is true on the client. The portrait is client-side.

Nothing loads / crash on startup

Check the Occultism version — the jar needs Occultism 1.224.0 or newer on NeoForge 1.21.1. The version range is enforced in the mod metadata, so a mismatch shows up as a loading-screen error rather than a crash.
