## FAQ
**Does it support Folia?** Not yet; there is no Folia build for 26.3. The code is structured for it.
**Spigot/Bukkit?** No, Paper only.
**Where do sales fees go?** They are removed from the economy.
**CMI?** CMI's economy needs CMI's Vault bridge (CMI Injector); without a Vault economy provider JustAuction disables itself with a clear message.
**What happens to unclaimed items?** They wait in `/ja claim` for `claim-retention-days` (default 7), then they are deleted.
