🛠️ OpacFixes
Server-side utility mod for Open Parties and Claims (OPAC) on Minecraft Forge 1.20.1.
OpacFixes adds admin-focused claim management commands and improves chunk forceload reliability in performance-heavy modpacks.
✨ What this mod does
🔍 Find player claims fast
Use /openpac-find <username> to list a player's claims (including offline players from the claim index), with clickable admin actions.
🧹 Wipe claims safely
Use /openpac-wipe <username> [dryrun] to remove all claims for a player across dimensions.
dryrun lets you preview how many chunks would be affected.
⚙️ Forceload reliability improvements
Adds extra enforcement layers so OPAC forceloaded chunks are less likely to unload when other mods alter ticket/chunk behavior.
