Alien | Rimworld - No Sleep Nightmares

A small Harmony patch for the "Alien | Rimworld" mod by Nighzmarquls (workshop id 3596077324).

PROBLEM
After being attacked by xenomorphs, colonists get a "VictimNightmareMood" debuff every single time they sleep, forever. The only intended cure is to make the traumatized colonist personally kill xenomorphs (or a queen) for "trauma relief", which is intrusive and easy to miss.

WHAT THIS PATCH DOES
Blocks the sleep-triggered VictimNightmareMood thought from ever being created. Implementation: Harmony Prefix on Xenomorphtype.XMTUtility.GiveMemory that returns false when the requested ThoughtDef is VictimNightmareMood.

WHAT IS PRESERVED
- All event-based mood thoughts (Cocooned, Chestburst, ParasiteLatched, Grabbed, Ovomorphed, etc.) still fire ONCE per actual attack and decay normally.
- JellyPod healing during sleep still works.
- Horror awareness still accumulates and still affects RestRateMultiplier.
- Mental break workers, obsession path, queen mechanics, all unchanged.
- Existing kill-relief mechanic still works (just no longer required).

LOAD ORDER
Load AFTER "Alien | Rimworld" and AFTER Harmony.
