What's new

1.6.6

Added

  • Persistent attack and defense cooldown windows for war declarations, including saved slot usage after restarts.
  • Configurable cooldown durations and target-chunk limits for each role.
  • war/side-cooldowns.dat for persisted cooldown state.
  • A separate /claimrules assembly rule for Create and Sable contraption assembly.
  • Settings for global war notifications, bossbars, and Xaero markers.

Changed

  • Updated the mod version to 1.6.6.
  • Daily outgoing and incoming war-start limits are disabled by default (0) but remain available as optional additional quotas.
  • Post-war protection now applies to all claims owned by the defending side rather than individual chunks.
  • Replaced max_active_wars_per_party with role-specific cooldown limits; a side cannot attack and defend at the same time.
  • /claimrules create now covers only Create and Offroad mining machines; assembly is controlled through /claimrules assembly.
  • Removed storage-specific protection, leaving container access and breaking behavior to vanilla and OPaC.
  • Villager, wandering trader, and Wither protections are disabled by default and remain configurable opt-ins.
  • War notifications, bossbars, and Xaero markers for active/preparing wars are visible to all compatible players by default; settings can restore side-, admin-, and radius-based filtering.

Fixed

  • Fixed denied Sable assemblies potentially leaving an orphan sub-level and causing a critical server error.
  • Fixed Sable assembly bounds detection, removing misleading reflection warnings and unnecessary fallback handling.
  • Create and Sable assemblies now validate all eight source AABB corners when crossing claims.

Notes

  • The first successful declaration starts fixed windows: 2 hours for the attacker and 1 hour for the defender by default.
  • Later successful starts consume slots without extending the window.
  • A duration of 0 disables only the timed quota, not the concurrent-war limit.
  • Xaero markers contain active-war metadata only and never expose a global claim-owner map.
